Abstract: The invention provides a variable optical attenuator or array with low PDL by using an embedded polymer channel waveguide with a plurality of resistive heaters fabricated on the top cladding of the polymer waveguide. The resistive heaters create a strong thermal gradient in the polymer layer stack which is associated with a strong refractive index gradient with the lowest refractive index under the heater. This refractive index gradient causes the optical mode in the channel to shift towards the buffer layer. Attenuation is induced by transition losses between heated and unheated regions in the polymer waveguide when an optical signal passes through these regions of the polymer waveguide.

Abstract: The present invention relates to a variable optical filter that can be used to filter an incoming signal, attenuate an incoming signal or in one configuration switch an incoming signal from one path to another. The present invention has found that an accurate and economical variable optical filter can be created by using an elastomeric material having a high coefficient of expansion in cooperation with a means for locally varying the temperature of the elastomeric material as an actuator for moving a reflective surface within the optical filter. The actuator can be operated in a controlled manner for example, to effect a tilt of the reflective surface for switching or attenuating an optical signal, or to vary the resonant wavelengths of a resonant cavity between partially reflective surfaces. In accordance with the invention there is provided, a variable optical filter comprising an input port and an output port; a first at least partially reflective disposed to receive a beam of light launched from the input port; an elastomeric material for supporting and varying the position of the at least partially reflective surface with respect to the input port; a heater for applying variable amounts of heat to the elastomeric material to move or pivot the at least partially reflective surface relative to the input port; and, control means for controlling the heater and for providing a signal to apply variable amounts of heat.
