Abstract
An optical cross switch including an improved system to align optical components is described. The system utilizes a highly transmissive sensor positioned in the optical path of an optical signal to determine the precise position of the optical signal. A feedback loop uses output from the highly transmissive sensor to readjust elements that maintains the optical signal in a desired position. The current system is particularly suitable for use in an optical cross switch.
Claims24
An optical system to control an optical signal, comprising:
- an array of beam defecting devices
- an array of receiving devices to receive the optical signal from a beam deflecting device in the array of beam defecting devices
- a highly transmissive sensor through which the optical signal passes, the sensor to detect and determine a position of the light signal the optical system using the determined position to adjust the beam defecting device in the array of beam defecting devices to allow the optical signal to reach a receiving device in the array of receiving devices.
An optical switching system to direct an optical signal comprising:
- a first array of movable mirrors including a first movable mirror;
- a second movable mirror to receive optical signals from the first movable mirror and direct the optical signal to a selected optical fiber;
- a first highly transmissive sensor to detect the position of the optical signal and signal when the optical signal is not directed to the selected optical fiber, when the optical signal is directed to the selected optical fiber, the optical signal passes through the first highly transmissive sensor into the selected optical fiber.
