Abstract

Optical integrated circuits are disclosed having a gap (18) traversing the lens or the waveguide grating and an actuator (12) that controllably positions the optical integrated circuit on each side of the gap (18). As a result, the thermal sensitivity of the optical integrated circuits, for example, arrayed waveguide gratings, is mitigated. Also disclosed are methods for fabricating optical integrated circuits employing the gap (18) and the actuator (12).

Description

technical field

[0001] The present invention relates to the field of optical integrated circuits, and more particularly to apparatus and methods for providing arrayed waveguides with a temperature-independent center wavelength. Background technique

[0002] Optical integrated circuits (OICs) come in many forms, such as 1xN optical splitters, optical switches, wavelength division multiplexers (WDMs), demultiplexers, optical add-drop multiplexers (OADMs), and others. These OICs are employed in building optical networks in which optical signals are transmitted between optical devices for carrying data. For example, traditional handshaking within telecommunications and data communication networks, in which electrical signals are transmitted via electrical conductors, is being replaced by optical fibers and light circuits, which transmit optical (eg, light) signals. These optical signals may carry data or other information through modulation techniques for transmission of such i...
