The behavior of a MSM traveling wave photodetector (TWPD) was studied under high optical power illumination and high bias level using electrical-optical sampling technique. Ultra-high bandwidth and reasonable quantum efficiency were obtained. Improved high power performance was also demonstrated in the device. Large photo-absorption volume and better capability of handling high bias voltage without breakdown accounted for the superior performance of the device. Under high bias and high optical power regime, carrier multiplication or lifetime increasing effect were found to be the dominating nonlinear mechanism.
