Disturbance tolerant optical device

摘要

In one embodiment, an optical device having a first and second group of the plurality of sensors is disclosed. The first and second group of the plurality of sensors may have a first and second center of gravity region respectively. The plurality of sensors may be arranged such that the first and second center of gravity region may be substantially overlapping so as disturbances created by a time varying field on the first and second group of the plurality of sensors may be substantially similar in magnitude. In another embodiment, a fiber optic transmission system having first and second groups of the plurality of sensors being arranged around a center of gravity region is disclosed. In yet another embodiment, an optical transceiver having first and second sets of the plurality of sensors arranged such that center of gravity of each group is formed at the center region is disclosed.

主权项

1. An optical device for sensing incident light that is indicative of a signal, comprising:
a plurality of sensors arranged in a substantially co-planar arrangement configured to generate photo-signals; a first group of the plurality of sensors being configured to be exposed to the incident light; a first center of gravity region of the first group of the plurality of sensors; a second group of the plurality of sensors being configured to be shielded from the incident light; a second center of gravity region of the second group of the plurality of sensors, wherein the first and second center of gravity regions are substantially overlapping such that disturbances created by a time varying field on the first and second groups of the plurality of sensors are substantially similar in magnitude; and a circuit configured to determine an indication of the signal, wherein the circuit has an output that is substantially independent from the disturbances created by the time varying field.
