Optical component

An optical component comprising:

• at least one first waveguide, the at least one first waveguide comprising at least one partially reflective output end facet, wherein light passing the at least one partially reflective output end facet of the at least one first waveguide propagates along a first propagation direction, and
• at least one second waveguide receiving the light passing the at least one partially reflective output end facet of the at least one first waveguide at an input end facet of the at least one second waveguide and guiding the light in a second propagation direction,
• wherein the at least one partially reflective output end facet and the input end facet are spaced from each other,
• wherein the at least one first waveguide and the at least one second waveguide are arranged such that the first propagation direction and the second propagation direction are different,
• wherein the at least one partially reflective output end facet is normal to the first propagation direction, and the input end facet is not normal to the second propagation direction,
• wherein an angle (θ) between the first propagation direction and the second propagation direction is equal to an angle of refraction at the input end facet, wherein a rotation of the at least one second waveguide is set to exactly match the angle of refraction at the input end facet, and
• wherein the at least one second waveguide is a tapered waveguide, the tapered waveguide having a cross-sectional area decreasing along a direction away from the input end facet.
