Directly Reflectivity Modulated Laser (01 January 2018)

We report a novel directly reflectivity modulated laser (DRML) whose output is modulated through a Michelson interferometer reflector of the laser cavity. 

25/40 Gb/s on-off-keying and 25 Gb/s binary phase-shift keying signals are generated and the wavelength tunability is >20 nm.
