    Abstract: Methods and apparatus for calibrating a gyroscope without rotating the instrument. In one example, a calibration method includes operating the gyroscope in a self-oscillation loop to generate x-axis and y-axis drive signals, adding forcing signals to the x-axis and y-axis drive signals to produce pick-off x-axis and y-axis signals, measuring the pick-off x-axis and y-axis signals to produce measurement data, determining a relative phase between the pick-off x-axis and y-axis signals, based on the measurement data and the relative phase, estimating parameters of the gyroscope, based on the measurement data and the estimated parameters, calculating estimated position signals to calibrate the gyroscope.

    Abstract: MEMS-actuated optical switches can be implemented on photonic chips. These switches are compact, essentially planar, simple to implement and include only one moving MEMS component per switch. The switches exhibit low optical loss, require low power to operate, and are simple to control and easy to integrate with other optical devices. Each switch has two optical waveguides that are optically coupled in an ON switch state and not coupled in an OFF switch state. An end or a medial section of one of the two waveguides may translate between the ON and OFF states to affect the coupling. Alternatively, a coupling frustrator may translate between the ON and OFF states to affect the coupling.
