1060nm Vernier-Tuned Distributed Bragg Reflector (VT-DBR) Laser for Swept-Source OCT
Frontiers in Optics 2015, 2015 We report the first wavelength-tunable 1060nm VT-DBR laser for use in SS-OCT applications. Electrical measurements demonstrate 1-3 nanosecond step response times for wavelength tuning. Optical linewidths less than 10 MHz are measured using self-homodyne interferometry.

Preparation and novel photoluminescence properties of the self-supporting nanoporous InP thin films
Scientific Reports, 2020 Self-supporting nanoporous InP membranes are prepared by electrochemical etching, and are then first transferred to highly reflective (> 96%) mesoporous GaN (MP-GaN) distributed Bragg reflector (DBR) or quartz substrate. By the modulation of bandgap, the

A wavelength-tunable short-cavity DBR laser with active distributed Bragg reflector
IEICE Electronics Express, 2005 The incorporation of an active single-quantum well in the tuning layer of a DBR laser is proposed as a way of compensating for optical loss and achieving stable single-mode operation during wavelength tuning. Experimental results demonstrate that the structure achieves these goals while maintaining the efficiency of tuning.
