We report on composite hybrid plasmonic waveguides (CHPW) which shows, record experimental attributes such as normalized Purcell factor approaching 10^4, 10-dB amplitude modulation with <1 dB insertion loss and fJ-level switching energy, and photodetection sensitivity and internal quantum efficiency of -54 dBm and 6.4 % respectively. These devices involve amorphous-based, CHPWs, with no crystalline material. The ability to support multiple optoelectronic phenomena while providing performance gains over existing plasmonic as well as dielectric counterparts offers a clear path towards reconfigurable, monolithic plasmonic circuits.
