Abstract
A platform taper is formed in an optical chip. A light-transmitting medium is attached to the optical chip after forming the platform taper in the optical chip. An waveguide taper is formed in the light-transmitting medium such that the waveguide taper and the platform taper are aligned so as to form an optical taper on the optical device.
Claims22
A method of forming an optical device, comprising:
- forming a platform taper in an optical chip;
- bonding a second optical chip to the optical chip after forming the platform taper in the optical chip, the second optical chip including a light-transmitting medium;
- and
- forming a waveguide taper in the light-transmitting medium, the waveguide taper and the platform taper being aligned so as to form an optical taper on the optical device.

An optical device, comprising:
- a waveguide layer on a base, the waveguide layer including a waveguide taper optically aligned with a waveguide, the waveguide taper including a light-transmitting medium;
- a platform taper between the waveguide taper and the base, the platform taper including the light-transmitting medium;
- and
- the light-transmitting medium included in the waveguide taper being bonded to the light-transmitting medium included in the platform taper such that the light-transmitting medium included in the waveguide taper is in direct contact with the light-transmitting medium included in the platform taper and a lattice of the light-transmitting medium in the waveguide taper is not continuous with a lattice of the light-transmitting medium in the platform taper.
