TWO COLOR DETECTOR LEVERAGING RESONANT CAVITY ENHANCEMENT FOR PERFORMANCE IMPROVEMENT

TWO COLOR DETECTOR LEVERAGING RESONANT CAVITY ENHANCEMENT FOR PERFORMANCE IMPROVEMENT

Methods and structures for providing single-color or multi-color photo-detectors leveraging cavity resonance for performance benefits. In one example, a radiation detector (110) includes a semiconductor absorber layer (210, 410A, 410B, 610, 810, 1010, 1030, 1210, 1230) having a first electrical cond...

Zusammenfassung:Methods and structures for providing single-color or multi-color photo-detectors leveraging cavity resonance for performance benefits. In one example, a radiation detector (110) includes a semiconductor absorber layer (210, 410A, 410B, 610, 810, 1010, 1030, 1210, 1230) having a first electrical conductivity type and an energy bandgap responsive to radiation in a first spectral region, a semiconductor collector layer (220, 630, 830, 1020, 1040) coupled to the absorber layer (210, 410A, 41013, 610, 810, 1010, 1030, 1210, 1230) and having a second electrical conductivity type, and a resonant cavity coupled to the collector layer (220, 630, 830, 1020, 1040) and having a first mirror (240) and a second mirror (245).
