High Focusing-reflection Subwavelength Gratings with Uni-traveling-carrier Photodetector for High Responsivity

Chen, Qingtao
Subjects: Electronics and Communication Technology >> Optoelectronics and Laser

High focusing-reflection, non-periodic high-contrast grating integrated with a uni-traveling-carrier photodetector (FR-UTC-PD) is proposed to overcome the bandwidth-responsivity trade-off. The responsivity of the FR-UTC-PD is increased by 36.5% while achieving a 3-dB bandwidth of 18 GHz.
