An integrated optical component includes at least one input waveguide, at least one output waveguide; a first slab waveguide having a first refractive index, n. The first slab waveguide may be disposed between at least one of the input waveguides and at least one of the output waveguides. The integrated optical component may further include a second slab waveguide having a second refractive index, n. The integrated optical component may also include a third cladding slab having a third refractive index, n. The third cladding slab may be disposed between the first slab and the second slab. The thickness of the second slab waveguide and the thickness of the third slab waveguide are adjustable to reduce a birefringence of the integrated optical component.

Polarization independent multiplexer / demultiplexer

In an example, a system includes a grating coupled laser and a photonic integrated circuit. The grating coupled laser includes a first waveguide and a transmit grating coupler optically coupled to the first waveguide. The photonic integrated circuit includes a second waveguide and a receive grating coupler optically coupled to the second waveguide. The second grating coupler may include a negative angle grating coupler.

Negative angle grating coupler

An integrated optical component includes at least one input waveguide, at least one output waveguide; a first slab waveguide having a first refractive index, n1. The first slab waveguide may be disposed between at least one of the input waveguides and at least one of the output waveguides. The integrated optical component may further include a second slab waveguide having a second refractive index, n2. The integrated optical component may also include a third cladding slab having a third refractive index, n3. The third cladding slab may be disposed between the first slab and the second slab. The thickness of the second slab waveguide and the thickness of the third slab waveguide are adjustable to reduce a birefringence of the integrated optical component.
