Abstract:
Using numerical simulation, the role of counter-connected tunnel diodes in multijunction monolithic photoconverters is investigated when they are illuminated by subnanosecond powerful laser pulses. It is shown that in this case, unlike stationary laser radiation, tunnel diodes are no longer key elements of a multijunction photoconverter, without which its operation is impossible, since tunnel currents are replaced by bias currents. For the first time, using the example of two-, three- and six-junction $p$–$i$–$n$ photoconverters operating in a pulsed mode, the possibility of their operation either without tunnel diodes or with a significant reduction in the requirements for their parameters is shown.
