Abstract
Techniques related to optical devices including a high contrast grating (HCG) lens are described herein. In an example, an optical device includes a transparent substrate. A laser emitter or detector at a first side of the transparent substrate to emit or detect a laser light transmitted via the transparent substrate. A HCG lens is at a second side of the transparent substrate to transmit and refract the laser light.
Claims20
An optical device, comprising:
- a transparent substrate;
- a laser emitter or a detector at a first side of the transparent substrate to emit or detect a laser light transmitted via the transparent substrate;
- and
- a high contrast grating HCG lens at a second side of the transparent substrate to transmit and refract the laser light.
(canceled)
An optical communication device, comprising:
- a transparent substrate;
- a vertical-cavity surface emitting laser VCSEL integrated at a first side of the transparent substrate to emit a modulated laser light into the transparent substrate, the laser light being modulated for transmitting information;
- an optical waveguide to implement optical communications to a remote device via transmission of the modulated laser light;
- and
- a HCG lens integrated at a second side of the transparent substrate to:
- receive the modulated laser light from the transparent substrate, and
- transmit and refract the modulated laser light into an optical input of the optical waveguide.
(canceled)
A method of manufacturing an optical device, the method comprising:
- integrating a laser emitter or detector at a first side of a transparent substrate;
- integrating a HCG lens at a second side of the transparent substrate to define an optical path coupling the laser emitter or detector and the HCG lens via the transparent substrate.
