Abstract :
We propose and analyze the bandwidth and efficiency issues of surface-plasmonresonance (SPR) enhanced metal-semiconductor-metal traveling-wave photodetectors. With strong field confinement near the nano-sized metal fingers, SPR-effect is found to greatly enhance the device¿s highspeed performance.
