Abstract
A detector remodulator comprising a silicon on insulator (SOI) waveguide platform including: a detector coupled to a first input waveguide; a modulator coupled to a second input waveguide and an output waveguide; and an electrical circuit connecting the detector to the modulator; wherein the detector, modulator, second input waveguide and output waveguide are arranged within the same horizontal plane as one another; and wherein the modulator includes a modulation waveguide region at which a semiconductor junction is set horizontally across the waveguide.
Claims27
A detector remodulator comprising:
- a silicon on insulator (SOI) chip;
- a detector coupled to a first input waveguide;
- a SiGe or homogeneous Si modulator, on the SOI chip, coupled to a second input waveguide and an output waveguide;
- and
- an electrical circuit connecting the detector to the modulator;
- wherein the modulator includes a waveguide including a modulation region at which a semiconductor junction is set across the waveguide of the modulator, the junction comprising a first doped region and a second doped region;
- wherein:
- the electrical circuit is connected to a first electrical pad on a first side of the modulation region, the first electrical pad forming a contact directly to the first doped region,
- the electrical circuit is connected to a second electrical pad on a second side of the modulation region, the second electrical pad forming a contact directly to the second doped region, and
- the electrical circuit comprises a signal path from the detector to the modulator, the signal path having a portion in an integrated circuit.
