Abstract

A Grating Based hybrid-Plasmonic-waveguide with subwavelength optical-confinement is proposed which exhibits large-propagation-length with low-modal-propagation-loss. The Grating is formed in Si region by varying the grating period and duty cycle. The thickness of the grating region is 600 nm and the grating period is 700 nm. The mode is confined in the 10 nm SiO₂ region. The Si layer below the SiO₂ provides the large propagation length of 4 mm with low modal propagation loss of 1 dB/mm with subwavelength mode confinement 0.00079/ μm² is obtained.
