Latest Patents

Takahashi holds a patent for a semiconductor laser and method for production thereof. This invention features a distributed feedback semiconductor laser that achieves a phase shift for stabilizing the longitudinal mode without a substantial increase in reactive current. The design avoids introducing dimensional discontinuities in the laser stripe. The active layer of the laser is configured as a multi-quantum well, with impurities selectively diffused into the multi-quantum well to disorder a selected portion of the active layer. This disordered portion has an optical propagation constant that differs from that of the remaining stripe. The difference in propagation constant, coordinated with the length of the phase adjustment section, produces a phase shift adequate to stabilize the laser longitudinal mode. Takahashi's innovative approach has led to advancements in laser technology.
