Abstract

A laser structure enabling simultaneous emission into distributed feedback (DFB) and distributed Bragg reflector (DBR) modes is characterized regarding frequency-shift keying (FSK)-modulated millimeter wave generation. Nonreturn-to-zero (NRZ)-modulation characteristics are measured by using time-resolved spectrum measurement techniques. A high FM efficiency of about 1.3 GHz/mA is reported at 622 Mb/s for 100-GHz-range millimeter waves.
