摘要： The present disclosure provides a system, apparatus and method to for providing highly manufacturable compact optical structures in optical circuits, increasing overall yield and lowering manufacturing costs. According to one aspect, an optical circuit is provided which includes an multimode interference element and first and second waveguides. The first waveguide may be provided adjacent a first side of the optical device and extending along at least the length of the multimode interference element, while the second waveguide may be provided adjacent a second side of the multimode interference element and extending along at least the length of the optical device. Each of the first and second waveguide have first and second ends which may be configured to dissipate propagating light in the first and second waveguides. The first waveguide may be spaced a first distance from the multimode interference element, the first distance being substantially constant along the length of the multimode interference element, and the second waveguide may be spaced a second distance from the multimode interference element, the second distance being substantially constant along the length of the multimode interference element. The first and second distances may be selected such that the first and second waveguides provide sufficient fabrication loading to maintain a width of the optical device along, a length of the optical device, within a deviation or range of values. In certain embodiments, the multimode interference element may be a multimode interference optical coupler.

摘要： The present invention provides for a semiconductor laser having a narrow linewidth and low power consumption for optical communication applications. According to various embodiments of the invention, a semiconductor laser is provided which includes a grating layer comprising a plurality of segmented gratings, each including a non-grating portion and a grating portion. The segmented gratings are configured to enhance a fundamental mode of the semiconductor laser while sufficiently suppressing modes other than the fundamental mode, providing a narrow linewidth for example. The segmented gratings are also configured to provide an effective length longer than an actual length of the semiconductor laser, leading to smaller device areas and corresponding lower power consumption. A photonic integrated circuit is also provided which includes a plurality of semiconductor lasers, consistent with the present invention, as well as additional optical elements, all provided on a single substrate.

摘要： Consistent with the present disclosure, a compact laser with extended tunability (CLET) is provided that includes multiple segments or sections, at least one of which is curved, bent or non-collinear with other segments, so that the CLET has a compact form factor either as a singular laser or when integrated with other devices. The term CLET, as used herein, refers to any of the laser configurations disclosed herein having mirrors and a bent, angled or curved part, portion or section between such mirrors. If bent, the bent portion is preferably oriented at an angle of at least 30 degrees relative to other portions of the CLET. Alternatively, the curve or bend portion may be distributed over different sections of the CLET over a series of arcs, for example. The waveguide extending between the mirrors is continuous, such that light propagating along the waveguide is not divided or split. The waveguide also constitutes a continuous waveguide path.

摘要： Consistent with the present disclosure, an optical receiver is paired with an optical transmitter in a transceiver card or module, for example. During normal operation, the optical transmitter supplies optical signals for downstream transmission on a first optical communication path, and the optical receiver receives additional optical signals from a second optical communication path. During a transmitter monitoring mode (or “loopback”), however, when monitoring of transmitter parameters is desired, an optical switch directs the output or portion thereof from the transmitter to the receiver. The receiver may then supply monitoring data or information to a control or processor circuit, which, in turn, may supply control signals to the transmitter. In response to such control signals, the performance of the transmitter may be optimized, for example, by reducing BER and/or OSNR to a desired level. The switch is then configured to block transmission of the transmitter output or portion and normal operation is commenced. Thus, consistent with the present disclosure, an optical receiver is provided to detect optical signals inbound on one optical communication path during normal operation is also used to receive optical signals directly from the transmitter during the monitoring mode. Accordingly, a dedicated monitoring receiver is not required and the system is rendered less expensive, power consumption may be minimized and space may be conserved.

摘要： The present invention provides a system, apparatus and method to maintain the polarization state of an optical signal propagating within a photonic integrated circuit, or from a first photonic integrated circuit to a second photonic integrated circuit. According to various embodiments of the invention, an optical circuit is provided which includes a waveguide having one or more bends or curved portions. The bends or curved portions of the waveguide are configured to maintain the polarization orientation of the optical signal as the optical signal propagates through the waveguide, such that the polarization orientation at inputs or outputs, or at various points along the waveguide is known. Embodiments of the present invention mitigate polarization crosstalk, which in turn provides for improved processing efficiency.
