Sgdbr Single-Chip Wavelength Tunable Lasers For Swept Source Oct, Dennis J. Derickson, Mike Bernacil, Andrew Dekelaita, Ben Maher, Shane O'Connor, Mathew N. Sysak, Leif Johanssen

Electrical Engineering

Sampled Grating Distributed Bragg Reflector (SGDBR) monolithic tunable lasers are now entering the production phase in telecommunications applications. These tunable lasers are unique in that they offer wide wavelength tuning (1525 to 1565 nm), fast wavelength tuning (5 ns) and high speed amplitude modulation all on the same monolithic chip1,2,3,4. This work studies the applicability of SGDBR monolithic tunable laser diodes for biomedical imaging using swept-wavelength or Fourier domain optical coherence tomography. This paper will present our work involved with utilizing the strengths (table 1) of this SGDBR laser class and mitigating the weaknesses (table 2) of this device for …
