ABSTRACT:
An optical signal low energy method for coupling electrical signals on-chip between component circuits of for example a CMOS circuit array. The described coupling method employs infrared signals communicated along a nano-scale resonant semiconductor waveguide between for example PIN diode signal transducers. The coupling may employ an electrically pumped laser, an electro absorption modulator and a photodetector all for typically the 1.5 to 2.0 micrometer spectral region with each formed using for example PIN heterodiode semiconductor devices. Each of these three devices includes active semiconductor crystal material situated in a resonator within a strip waveguide. The resonator is defined by two fabricated mirrors having a tapered location one dimensional photonic crystal lattice of oxide hole or slot apertures. Each semiconductor device is for example a heterodiode pumped or controlled by laterally disposed wings enclosing the resonator to form a lateral PIN structure for current injection or high E-field generation. CMOS compatible ten gigabit per second signals of low energy use per transmitted bit are achieved.
