“…Moreover, the transport time roll-off is now determined by the transit time τ tr . The transit-time roll-off [7] depends on the design of the photodiode and does not follow a simple expression as obtained for the recombination roll-off in equation (5). To a reasonably good approximation, however, I pin 0 (ν THz ) can be written as…”

We report on a novel concept for THz photomixers with high conversion efficiency up to several THz. In contrast to the conventional pin photomixer we can overcome the trade-off between either optimizing transit-time or RC-roll-off. Using quasi-ballistic transport in nano-pin-diodes the transport path can be optimized regarding both path length and transit time. Independently, the capacitance can be kept small by using a sufficiently large number of optimized nano-pin-diodes in series. The concept is presented in detail and first experimental results are reported which corroborate our theoretical expectations.
