Abstract :
Traveling wave photodetectors (TWPD) are promising devices for high bandwidth and high efficiency. In this paper, electro-optic sampling measurements of this novel self-aligned metal-semiconductor-metal TWPD under different biases and pumping levels are performed at a wavelength of 810 nm and the electrical sampling measurements are performed at a wavelength of 1230 nm.
