    Abstract: Embodiments herein relate to a photonic integrated circuit (PIC) with an on-chip optical isolator. The PIC may comprise a laser, a waveguide, and a closed loop resonator coupled to the laser through the waveguide. A magneto-optical layer is over and in contact with the waveguide and the closed loop resonator. The closed loop resonator may comprise a first polarization rotator (PR) and a second PR. A light from the laser in transverse electric (TE) mode through the waveguide is rotated in the first PR to a light in transverse magnetic (TM) mode, and the light in TM mode is rotated in the second PR to light in TE mode. The isolator may comprise a micro-heater over or along a side of the waveguide and separated from the closed loop resonator; and a feedback control loop connected to the closed loop resonator and the micro-heater.

    Abstract: We disclose a photonic integrated circuit (PIC) having a first photonic chip and a second photonic chip that are bonded and optically coupled to one another in a manner that reduces the number of different photonic chips that need to be integrated into the same PIC package to achieve a desired electro-optical function. In an example embodiment, the first photonic chip may include active optical components, such as lasers and optical amplifiers, and be fabricated using the III-V semiconductor technology. The second photonic chip may include additional optical components, such as modulators, photodetectors, and passive optical components, and be fabricated using the CMOS technology. The second photonic chip may also include one or more 2x2 optical couplers configured to appropriately (re)direct various optical signals between the active optical components of the first photonic chip and the additional optical components of the second photonic chip to achieve the desired electro- optical function.

    Abstract: A Time Domain Optical Coherence Tomography system using a modulation scheme multiplexes the scanning range of the delay line into different spectral bands. Such a modulation scheme may allow for power consumption reduction compared with a single delay line element since the same modulation pattern is being used for several channels. In an example, the optical coherence tomography system may include a plurality of stages, each stage having a group delay element. The distinct group delays may be introduced to scan a sample with distinct electrical frequency bands at distinct axial scanning depth ranges.
