INTERFACE DEVICE FOR PERFORMING MODE TRANSFORMATION IN OPTICAL WAVEGUIDES
摘要
<p>An interface device for performing mode transformation in optical waveguides includes an optical waveguide core for propagating light of a particular wavelength. The optical waveguide core terminates in a subwavelength grating configured to change the propagation mode of the light. The subwavelength grating has a pitch sufficiently less than the wavelength of the light to frustrate diffraction. The device can thus serve as an optical coupler between different propagating media, or as an anti-reflective or high reflectivity device.</p>
