Wavelength tunable sampled grating distributed Bragg reflector (SG-DBR) lasers used for telecommunications
applications have previously demonstrated the ability for linear frequency ramps covering the entire tuning range of the
laser at 100 kHz repetition rates1. An individual SG-DBR laser has a typical tuning range of 50 nm. The InGaAs/InP
material system often used with SG-DBR lasers allows for design variations that cover the 1250 to 1650 nm wavelength
range. This paper addresses the possibility of concatenating the outputs of tunable SGDBR lasers covering adjacent
wavelength ranges for enhancing the resolution of OCT measurements. This laser concatenation method is
demonstrated by combining the 1525 nm to 1575 nm wavelength range of a "C Band" SG-DBR laser with the 1570nm
to 1620 nm wavelength coverage of an "L-Band" SG-DBR laser. Measurements show that SGDBR lasers can be
concatenated with a transition switching time of less than 50 ns with undesired leakage signals attenuated by 50 dB.
