摘要： Described are various configurations for performing efficient optical and electrical testing of an opto-electrical device using a compact opto-electrical probe. The compact opto-electrical probe can include electrical contacts arranged for a given electrical contact layout of the opto-electrical device, and optical interface with a window in a probe core that transmits light from the opto-electrical device. An adjustable optical coupler of the probe can be mechanically positioned to receive light from the device's emitter to perform simultaneous optical and electrical analysis of the device.

摘要： An optical device such as an optical transceiver can include a cascaded built-in self-test structure that can be configured in testing mode using an active power mode and can sufficiently attenuate light away from a loopback path in an inactive power mode. The optical device can include a wafer top emitter that can be used to tune a light source for testing and calibration of optical components while the built-in self-test structure is in active mode.

摘要： A symmetric distributed feedback (DFB) laser that is integrated in a silicon based photonic integrated circuit can output light from both sides of the symmetric DFB laser onto waveguides. The light in the waveguides can be phase adjusted and combined using an optical coupler. The symmetric DFB laser can generate light and symmetrically output light onto different lanes of a multi-lane transmitter.
