- 초록
- We present optimized structure of waveguide photodetector (WGPD) having large responsivity in spite that its absorption layer is thin. Through beam-propagation method simulations, spot-size converter integrated WGPD is found to be able to have larger responsivity with thinner absorbing layer. Calculated responsivity and polarization dependent loss of the optimized design are 0.83 A/W and 0.13 dB with 150-nm-thick and 25-μm-long absorber.
