摘要：
We propose, design, fabricate and characterize a subwavelength grating slot (SWGS) waveguide on sili-con platform at short-wave infrared (SWIR) wavelength of 2 mu m. The mode guiding mechanism, i.e. SWGS mode, is a combination of surface-enhanced supermode and Bloch mode. We also design and fabricate a low-loss strip-to- SWGS mode converter. We further demonstrate chip-scale direct modulation data transmission at 2 mu m through the fabricated SWGS waveguides. Favorable operation perfor-mance is achieved in the experiment.
