Embodiments of the disclosure pertain to a system for transferring an optical signal from one photonics chip or integrated circuit (PIC) to another. The system includes a first PIC having (i) an optical emitter or optical transmission mechanism and (ii) a focusing mirror thereon, and a second PIC having an optical receiver and a reflecting mirror thereon. The reflecting mirror is configured to reflect light transmitted by the optical emitter or optical transmission mechanism back to the first PIC. The focusing mirror is configured to (i) further reflect the light reflected by the reflecting mirror and (ii) focus the further reflected light on the optical receiver. Methods of using and manufacturing the system are also disclosed.

System and method for transferring optical signals in photonic devices and method of making the system

An optical phase shifter and a method of making the same are disclosed. The phase shifter includes a substrate, a p-doped electrode and an n-doped electrode on the substrate, a first doped semiconductor layer on the p-doped electrode or the n-doped electrode and in electrical contact with the other electrode, a second doped semiconductor layer on the first doped semiconductor layer, a first vertical region electrically connecting the second doped semiconductor layer with the one electrode, and a cladding layer on or over the second semiconductor layer, the first vertical region, and at least a first sidewall of each of the first and second semiconductor layers. The p-doped electrode and the n-doped electrode form a p-n junction at an interface therebetween. The first and second doped semiconductor layers have the same doping type as the other electrode and the one electrode, respectively.

Multi-layer p-n junction based phase shifter and methods of manufacturing and using the same

Embodiments of the disclosure pertain to an optical modulator including an m*n optical coupler, first and second waveguides coupled or connected to the m*n optical coupler, a first phase shifter coupled to the first waveguide, and first and second loop mirrors at respective ends of the first and second waveguides opposite from the m*n optical coupler. The m*n optical coupler is configured to combine substantially similar or identical continuous light beams (at least one of which may be phase-shifted) returned through the first and second waveguides by the first and second loop mirrors to form a modulated optical signal. A compound optical modulator, a modulated or modulatable laser, and methods of using and manufacturing the optical modulators, are also disclosed.
