BROADBAND OPTICAL COUPLING USING DISPERSIVE ELEMENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18448429 titled 'BROADBAND OPTICAL COUPLING USING DISPERSIVE ELEMENTS
Simplified Explanation
The patent application describes a system for coupling a fiber to a photonic chip using a collimating lens and an optical grating.
- The system includes a collimating lens that takes light from a light source and makes it parallel.
- An optical dispersion element separates the collimated light into multiple beams and directs each beam to a different section of the grating.
- Each beam is diffracted at a different wavelength, and the angle at which it hits the grating is based on its wavelength.
- This allows for optimal coupling between the fiber and the photonic chip.
Original Abstract Submitted
Embodiments include a fiber to photonic chip coupling system including a collimating lens which collimate a light transmitted from a light source and an optical grating including a plurality of grating sections. The system also includes an optical dispersion element which separates the collimated light from the collimating lens into a plurality of light beams and direct each of the plurality of light beams to a respective section of the plurality of grating sections. Each light beam in the plurality of light beams is diffracted from the optical dispersion element at a different wavelength a light beam of the plurality of light beams is directed to a respective section of the plurality of grating sections at a respective incidence angle based on the wavelength of the light beam of the plurality of light beams to provide optimum grating coupling.
