Numerical Modeling of InAs/InP Quantum Dash Ridge Lasers as a Function of Temperature Abstract: Mode‑locked semiconductor lasers based on InAs/InP quantum‑dash structures have emerged as promising, compact sources for broadband frequency‑comb generation, particularly for dense wavelength‑division multiplexing (DWDM) and other high‑capacity optical communication systems. In this work, we present a comprehensive numerical study of InAs/InP quantum‑dash ridge lasers, analyzing how device geometry, carrier dynamics, and dispersion properties influence the formation, stability, and bandwidth of the generated optical combs. Our modeling framework captures the interplay between gain recovery, saturable absorption, group‑velocity dispersion, and nonlinear phase modulation, enabling detailed predictions of pulse characteristics as a function of structural and operational parameters. We highlight design trade‑offs that optimize pulse duration, repetition rate, and comb flatness, and we discuss the implications of these results for integrated photonic systems requiring low‑cost, energy‑efficient comb sources. This analysis provides valuable guidelines for engineering next‑generation quantum‑dash mode‑locked lasers tailored to emerging communications and sensing applications. ------------------------------------------------------------------------ Modélisation numérique des lasers à tirets quantiques InAs/InP en fonction de la température Résumé: Résumé : Les lasers semi-conducteurs à modes verrouillés, basés sur des structures à points quantiques InAs/InP, se sont révélés être des sources compactes et prometteuses pour la génération de peignes de fréquences à large bande, notamment pour le multiplexage par répartition en longueur d'onde dense (DWDM) et d'autres systèmes de communication optique à haute capacité. Dans ce travail, nous présentons une étude numérique complète des lasers à crête à points quantiques InAs/InP, analysant l'influence de la géométrie du dispositif, de la dynamique des porteurs et des propriétés de dispersion sur la formation, la stabilité et la bande passante des peignes optiques générés. Notre modèle capture l'interaction entre la récupération du gain, l'absorption saturable, la dispersion de vitesse de groupe et la modulation de phase non linéaire, permettant des prédictions détaillées des caractéristiques des impulsions en fonction des paramètres structurels et opérationnels. Nous mettons en évidence les compromis de conception qui optimisent la durée des impulsions, la fréquence de répétition et la planéité du peigne, et nous discutons des implications de ces résultats pour les systèmes photoniques intégrés nécessitant des sources de peignes à faible coût et à haute efficacité énergétique. Cette analyse fournit des indications précieuses pour la conception de lasers à modes verrouillés à points quantiques de nouvelle génération, adaptés aux applications émergentes de communication et de détection.

The rapid proliferation of connected devices, autonomous systems, and data-driven services is transforming modern infrastructures into highly networked, intelligent ecosystems. From smart transportation and digital healthcare to disaster response and edge AI applications, these systems must not only deliver intelligence but also ensure resilience, privacy, and adaptability in dynamic and uncertain environments. This workshop brings together recent advances in intelligent networked systems that integrate distributed learning, privacy-preserving mechanisms, cooperative control, and edge intelligence. A central theme is the design of systems that remain reliable, secure, and efficient while operating under resource constraints, partial observability, and evolving network conditions.

IEEE Photonics Society Toronto is proud to invite you to a seminar by Dr. Federico Rosei of University of Trieste, Italy. Join us Tuesday, 24 February 2026 at 4PM (ET) on University of Toronto main campus. Refreshments will be served. Registration Required. Abstract --------------------------------------------------------------- The quest for sustainable development dictates an urgent transition from fossil fuels to renewables. This presentation focuses on next generation (solar) energy technologies from a materials perspective. We study structure property/relationships in advanced materials, emphasizing multifunctional systems that exhibit several functionalities. Such systems are then used as building blocks for the fabrication of various emerging technologies. In particular, nanostructured materials synthesized via the bottom–up approach present an opportunity for future generation low cost and low energy intensive manufacturing of devices. We focus on recent developments in solar technologies, including third generation photovoltaics, solar hydrogen production, luminescent solar concentrators and other optoelectronic devices, highlighting the role and importance of critical raw materials. --------------------------------------------------------------- --------------------------------------------------------------- Speaker(s): Dr. Federico Rosei, Room: 202, Bldg: Galbraith Building, 35 St George St, Toronto, Toronto, Ontario, Canada, Virtual: https://events.vtools.ieee.org/m/532572

Cardiovascular diseases are one of the leading causes of death worldwide. We will discuss our group’s recent efforts in using advanced medical imaging and machine-learning based finite-element modeling to better diagnose and treat various cardiovascular diseases. We will first present our group’s recent developments in physics-informed machine-learning that can be used to regularize sparse observational data by embedding know physical laws into the loss functions. We will demonstrate the performance of this framework in patient-specific vascular geometries (e.g., aorta, idealized arteries) and subsequently validation in real-world imaging data. We will also discuss our group's work in advanced medical imaging, and in particularly, CT myocardial perfusion imaging to better detect diseased heart vessels, specifically those that limit blood flow to the heart muscles. Lastly, we will discuss recent directions within our group to characterize durability of tissue-mimicking materials towards advancing and improving bioprosthetic heart valves.

Abstract: As industry is starting to deploy systems based on 224Gbps/lane and growing pains are becoming more apparent, AI companies are clamoring already for more bandwidth. A first look at 448Gbps is already highlighting the enormous challenges of running even very short links on copper. However, industry doesn’t seem yet ready to throw the towel on pluggable modules as gateways to optical interconnect given the risks and limitations of CPO. Some of the questions that will be covered: - Can we clearly articulate what are the priorities in developing the next generation of interconnect for AI? - What are the main obstacles to the adoption of short reach optics to replace the last inches of electrical connectivity? - What can we learn from advances in C2C and in particular by the success of UCIe? - Does it make sense to still have pluggable modules and what is the best way to do that? - Was LPO a success or a bust and can we move forward with it? - What are the promises and possible pitfalls of CPO? Topics touched upon: - System level (Computing, AI) requirements & considerations (architectural trends, efficiency, bw, latency, cost etc.) - Optical and electrical energy efficiency considerations - HW technology developments and limitations (interposer, packaging, connectors, cables) - System trade offs analysis (retiming vs. linear, vs. CPO) - Chiplets and co-packaging technology - Analysis of latest OIF development on next generation interconnect Agenda: Room: GB202, Bldg: Galbraith Building, University of Toronto, 35 St George Street, Toronto, Ontario, Canada
