Single Output Tunable DFB Semiconductor Laser Array with Equivalent Phase Shift

Not Accessible

Your library or personal account may give you access

Abstract

We report single output tunable DFB semiconductor laser arrays in series and grating-matrix configuration designed by reconstruction equivalent chirp (REC) technique. By using interference lithography and photolithography for the grating fabrication, tunable laser arrays with good performance are experimentally realized with low cost.
