Abstract :
A high-contrast, multiquantum well reflection modulator in series with a constant current source, gives a very efficient photodetector which only absorbs optical power in proportion to the fixed current. Excess optical power is reflected and can be passed on, via waveguide or free-space interconnects to other optical ´taps´ in a daisy chain configuration.
