Abstract

An automated heterodyne method is proposed to characterize sampled grating distributed Bragg reflector (SG-DBR) lasers in terms of their lasing output wavelength, side-mode suppression ratio (SMSR) and output power. Such lasers are the core of akinetic all-semiconductor based swept sources for Optical Coherence Tomography (OCT) systems. The purpose of the paper is to demonstrate the technique and obtain a broader optical and electrical understanding in DC and AC operation. A JDSU Agile SG-DBR laser was characterized and found to have a tuning range 60 nm, a center wavelength λc = 1540 nm and average lasing power of 10 mW. The result of the AC characterization is a a€tuning dictionary' that contains 379 tuning points (10 μs per tuning point).
