Abstract. Optical injection locking has been actively researched for its potential to improve ultrahigh frequency performance of semiconductor lasers for both digital and analog applications. We have proposed a new injection-locking scheme, based on unidirectional whistle-geometry ring lasers (WRLs) monolithically integrated with distributed Bragg reflector (DBR) laser masters. Numerical analysis of the modulation response of a single injection-locked WRL shows a very significant reduction in the modulation efficiency between low frequency and the resonance frequency (low-frequency roll-off), which severely limits the achievable 3-dB modulation bandwidth. By combining advantages of strong injection locking (to dramatically enhance the resonance frequency) and cascaded arrangement of WRLs (to eliminate the low-frequency roll-off in modulation response), a new class of high-performance, small-size, low-cost, ultrafast (over 100 GHz), easy-to-use functional chips is expected to emerge.



Marek Osiński is a Distinguished Professor of Electrical and Computer Engineering, Physics and Astronomy, and Computer Science at UNM. His main current research interests include semiconductor ring lasers, monolithically integrated optoelectronic circuits, quantum photoic integrated circuits, superconducting nanowire single-photon detectors, ultrafast optoelectronic devices, comprehensive simulation of optoelectronic devices, memristors, neuromorphic computing, colloidal nanocrystals for biomedical applications, nanoscintillators, and hybrid nanocrystals for solar hydrogen production. He is a Life Fellow of IEEE and a Fellow of the Optical Society of America and the International Society for Optical Engineering (SPIE). He has authored or co-authored over 540 technical papers, 7 book chapters, 22 awarded, and 7 pending patents. He also co-edited 28 books of SPIE conference proceedings on physics and simulation of optoelectronic devices and 21 other SPIE volumes in the fields of advanced high-power lasers, optoelectronics, nano-biophotonics, and colloidal nanoparticles for biomedical applications.
