Patent number: 9557484Abstract: 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.Type: GrantFiled: November 10, 2014Date of Patent: January 31, 2017Assignee: Aurrion, Inc.Inventors: Erik Johan Norberg, Jonathan Edgar Roth

Patent number: 8885679Abstract: Embodiments of the invention describe integrating a phase shifting component into a cavity of a laser. Said phase shifter is capable of a continuous phase shift at a single wavelength over a large range (where the maximum energy consumption of the phase shifting component does not scale with the phase shifting range). In other words, said phase shifter is used to form a configurable optical cavity length for a laser. Embodiments of the invention thus utilize a plurality of optical cavity lengths—including one or more optical cavity lengths to potentially shift the phase of the output optical signal, to maintain a laser cavity's output wavelength and avoid spatial mode-hops in the presence of fluctuations such as temperature drift or changes to the drive current of the laser.Type: GrantFiled: May 31, 2013Date of Patent: November 11, 2014Assignee: Aurrion, Inc.Inventors: Jonathan Edgar Roth, Gregory Alan Fish, Erik Johan Norberg, Robert Silvio Guzzon, Brian R.
