테이퍼 모드 변환기를 집적한 1.55-$\mu m$ 레이저다이오드의 설계
Design of 1.55-mm InGaAsP Laser Diode Integrated with a Tapered Ridge Mode Transformer
초록
A tapered ridge mode laser diode with increased spot size is designed and analyzed . The mode evolution concept is applied to design the taper and the method does not require regrowth or multiple-step etching technique. Three-dimensional BPM results show that the designed taper can transfer more than 97% of the mode power in the active region to the expanded mode.
