Abstract :
A laser structure having an active layer composed of several thin bulk layers is described. Buried ridge structure type Fabry-Perot lasers fabricated by using this structure exhibit a low internal loss of 15.6 cm-1 and a RC-limited modulation bandwidth as wide as 10 GHz. A reduced polarization sensitivity was demonstrated by a test optical amplifier
