Abstract

A double-channel planar buried-heterostructure semiconductor laser diode (DC-PBH LD) has improved high frequency response characteristics due to lower p-n junction capacitance resulting from the interposition of a low carrier concentration blocking layer between p-n-p-n blocking layers of the DC-PBH LD structure.
