High-speed operation of cleaved coupled cavity (C3) lasers made from double-channel planar buried-heterostructure (DCPBH) lasers operating at 1.5 μm wavelength is reported. Error-free (error rate<10−11/s) operation through a spectrometer at a data rate of 2 Gbit/s and with large on-off and mode rejection ratios is demonstrated. Small-signal bandwidth measurements indicate possible operation of these lasers up to about 4 Gbit/s.
