Our recent breakthrough development of Ultra-wideband QD Comb Laser with 24 lines with 100GHz spacing to be presented at Post Deadline Paper session at OFC 2025 on Thursday, April 4

Innolume will present a postdeadline paper at Optical Fiber Communication Conference (OFC) 2025, currently taking place in San Francisco. This marks the third consecutive year that our work has been selected for postdeadline sessions—following the 2023 presentation on "High-performance O-band QD DFB Laser for uncooled operation", V.Mikhrin et al, and the 2024 presentation on "High-Power O-band QD Booster Amplifier for Uncooled Operation", S.Poltavtsev et al.

This year's paper, titled "Ultra-Wideband, Flat-Top, 100 GHz Spacing Quantum-Dot Comb Laser for CW-WDM Data Transmission in O-Band," will be presented by Dr.Janina Rautert during Postdeadline Session IV (Th4D) on Thursday, April 3, at 5:00 PM in Room 207.

Innolume's QD Comb Laser at OFC 2025 Postdeadline

The presentation will introduce a Quantum Dot-based Comb Laser featuring a flat-top spectrum with 24 lasing lines with 100 GHz spacing. According to our knowledge we doubled the number of channels with 100GHz spacing compared to previously reported QD comb lasers. This device is designed for Coarse Wavelength Division Multiplexing (CW-WDM standard), addressing the disruptively growing demand for scalable and energy-efficient data transmission solutions in next-generation AI clusters and data centers.

Together with our previous post-deadline presentations at OFC 2024 and OFC 2023 the upcoming 2025 presentation highlights the broad portfolio of photonic devices developed by Innolume and underscore our leading role in advancing uncooled, high-performance QD lasers for next-generation optical interconnects.

We cordially invite you to attend the session as well as visit our booth (#4909) to learn more about our product portfolio.
