Abstract: A polymer well may be formed over a thermal oxide formed over a semiconductor substrate in one embodiment. The well may include a waveguide and a pair of heaters adjacent the waveguide. Each heater may be mounted on a platform of insulating material to reduce heat loss through the substrate and the thermal oxide, in one embodiment.

Abstract: Optical components may be integrated into planar light circuits. For example, thin film filters may be integrated through trenches in planar light circuits to achieve demultiplexing of at least two multiplexed optical wavelengths. An optical waveguide may be interfaced with a laser or a light detector through a mode converter formed as a trench in the planar light circuit. The mode converter may have a curved surface to achieve mode conversion.

Abstract: Optical components may be precisely positioned in three dimensions with respect to one another. A bonder which has the ability to precisely position the components in two dimensions can be utilized. The components may be equipped with contacts at different heights so that as the components come together in a third dimension, their relative positions can be sensed. This information may be fed back to the bonder to control the precise alignment in the third dimension.

Abstract: Methods for fabricating merged magnetic heads, employing an inductive write head and a magnetoresistive (MR) read head which share portions of the overall magnetic structure, provide for accurate definition of the write track width and for improved alignment of the write gap and the read gap. The method includes accurately forming and defining the nonmagnetic write gap prior to fabricating the inductive write coil structure and subsequently formed higher topology elements. The methods provide for better control of the widths of the top pole member and the bottom pole member, thereby resulting in substantially equal widths for these pole members.
