    Photonic-crystal-based resonant-cavity-enhanced detectors
    (IEEE, 1998) Temelkuran, Burak; Özbay, Ekmel; Kavanaugh, J. P.; Tuttle, G.; Ho, K. M.
    A layer-by-layer three-dimensional photonic crystal, with a full photonic bandgap (PBG) in all directions is proposed. The electrical fields in the cavities of this crystal are usually enhanced, and by placing active devices such as resonant cavity enhanced (RCE) photodetectors and light emitting diodes. The RCE effect is demonstrated by placing microwave detectors within localized modes of photonic crystal, along with a monopole antenna. A network analyzer measured the enhanced field. Such RCE detectors are more sensitive and efficient as compared to conventional detectors, and can be used for various applications where sensitivity and efficiency are important parameters.
