Abstract
In this paper the generation of MM and subwave signals by heterodyning two optical signals in a photo detector is considered. Previous work in this field has shown that this approach, is feasible. However, the work demonstrated so far exhibits very low power efficiency (< 1%) and low output power level (< 1 mw) for frequencies in the MM wave range. In this paper design considerations for an efficient traveling wave uni-traveling carrier PD are presented. Simple calculations are presented to estimate the bandwidth, microwave output power and power efficiency of this type of PD. The effect of the physical design parameters on the performance is discussed and design approach for high efficiency is presented. It is also shown that including the electron ballistic effect in the model suggests operation of the PD well into the sub-MM range.
