Abstract:
Embodiments describe high-efficiency optical waveguide transitions—i.e., creating heterogeneous transitions between Si and III-V semiconductor regions or devices with minimal reflections. This is advantageous for III-V device performance, e.g. for an on-chip lasers achieving lower relative intensity noise (RIN) and lower phase noise by avoiding reflections, higher gain and reduced gain-ripple from an semiconductor optical amplifier (SOA) by avoiding internal reflections in the SOA. Furthermore, in some embodiments, generated photocurrent can be used as a monitor signal for control purposes, thereby avoiding the use of separate tap-monitor photodetectors, which provide additional link loss.

Claim (Index 15):
A method for coupling light between waveguides, the method comprising:\n propagating light in a first waveguide to a coupling region of the first waveguide, the coupling region of the first waveguide being parallel to and directly adjacent to a second waveguide; coupling a first fraction of the propagating light from the first waveguide into the second waveguide at the coupling region of the first waveguide; retaining a second fraction of the propagating light in the first waveguide beyond the coupling region of the first waveguide, the first fraction and the second fraction summing to a value less than or equal to 100%; directing the second fraction of the light onto a structure coupled to first waveguide and configured to reduce back-reflections of light toward the coupling region.
