Redwan Islam received the best talk award at the Advances in 3OM and Photonics Technologies 2025 conference!

Congratulations to Redwan Islam for winning the best talk award at the Advances in 3OM and Photonics Technologies 2025 conference in Romania. The talk titled “Design and Characterization of Si3N4-GaSb Hybrid Laser for Gas Spectroscopy of CO2 around 2.7 um Wavelength” presented the design and experimental characterization of a hybrid-integrated laser targeting the 2.7 um absorption line of CO2. By combining a high-gain GaSb-based reflective semiconductor optical amplifier with a low-loss Si3N4 photonic integrated circuit (PIC) featuring a Distributed Bragg Reflector Microring Resonator (DBR-MRR) filter, it achieved a high-power, single-mode output of around 17 mW, significantly advancing the state-of-the-art for tunable Mid-IR sources.
