A photonic module, comprising a first waveguide; a second waveguide, disposed on an opposing side of the first waveguide to a substrate; and, a coupling section. One of the first waveguide and the second waveguide is formed of crystalline silicon. The other of the first waveguide and the second waveguide is formed of amorphous silicon. The coupling section is configured to couple light between the first waveguide and the second waveguide. Such a silicon photonic module has enhanced coupling and transmission properties in contrast to conventional modules.

Photonic module and method of manufacture

An optical out-coupler unit for out-coupling light from a waveguide, comprising a substrate having a planar top surface, a waveguide arranged on the top surface of the substrate and having a facet, a reflective surface, wherein the reflective surface is arranged spaced apart from the facet and opposing the facet, wherein the reflective surface is inclined with respect to a normal to the top surface of the substrate by more than 45°. The optical out-coupler may be part of a photonic integrated chip (PIC).

Optical out-coupler unit for out-coupling light from a waveguide

A photonic chip. In some embodiments, the photonic chip includes a waveguide; and an optically active device comprising a portion of the waveguide. The waveguide may have a first end at a first edge of the photonic chip; and a second end, and the waveguide may have, everywhere between the first end and the second end, a rate of change of curvature having a magnitude not exceeding 2,000/mm.

Optoelectronic device and array thereof

A photonic integrated circuit. In some embodiments, the photonic integrated circuit includes: a waveguide; and a waveguide facet, a first end of the waveguide being at the waveguide facet, a first angle being an angle between: the waveguide at the first end of the waveguide and the normal to the waveguide facet, the first angle being at least 5 degrees, a first section of the waveguide having a first end at the waveguide facet and a second end, the first section having: a curvature of less than 0.01/mm at the first end of the first section, a curvature of less than 0.01/mm at the second end of the first section, and a curvature of at least 0.1/mm at a point between the first end and the second end.

Waveguide facet interface

A waveguide mode filter. In some embodiments, the waveguide mode filter includes a first section of waveguide. The first section may have: a first end; a second end; a rate of change of curvature having a magnitude not exceeding 15/mmwithin the first section; a curvature having a magnitude of at most 0.03/mm at the first end; and a curvature having a magnitude of at least 0.1/mm at the second end.

Higher order mode filter

A waveguide grating. The waveguide grating includes a rib composed of a first material. A first portion of the waveguide has a first layer on the rib, the first layer being composed of a second material; and a second layer on the first layer, the second layer being composed of a third material, the third material having a higher index of refraction than the first material.
