Minimized transient wavelength and power variations on the DFBLDs for 200Mbit/s DPS phase shift keying

Abstract

Transient wavelength and power stability of two DFBLDs with sub-MHz linewidth are compared to provide differential logarithmic wavelength and power variations within 1×10-5% (▵lnλ) and 0.03% (▵lnP), respectively, for high-security DPS phase-shift-keying encoding/decoding at 200Mbit/s.
