Embodiments of an optical device, an array of optical devices, and a technique for fabricating the optical device or the array are described. This optical device is implemented on a substrate (such as silicon), and includes a thermally tunable optical waveguide with a high thermal resistance to the surrounding external environment and a low thermal resistance to a localized heater. In particular, the thermal resistances associated with thermal dissipation paths from a heater in the optical device to an external environment via electrodes and via the substrate are increased, while the thermal resistance between the optical waveguide and the heater is decreased. The heater element consists of a doped semiconductor layer with a rib waveguide (424) on top embedded in a surrounding cladding layer (416) having regions of high doping for improving electrical and termal contact between the electrode (418-1, 418-3) and via material (418-2, 418-4, 420-2, 420-1) and the heater part, (426-2, 422, 426-1). |

Electric fields are used to raise the index of refraction of one side branch waveguide above the index of the center branch waveguide and to lower the index of refraction of the other side branch below the index of the center branch waveguide. The switch has an extinction ratio of 700:1 (28 dB) between its two side branches. | ||||||

A modulator formed with a solid state electro-optic material having a pixellated structure interconnected to a circuit on a semiconductor substrate. Silicon CMOS integrated circuit that can include random access memories (RAMs) are used as a substrate and interfaced to solid state electro-optic materials coated thereon. In particular, the electro-optic modulators are controlled by RAM cells to produce a modulation of reflected light. SRAMs can be used with connection to the SRAM cell flip-flop. DRAMs can be used with the modulator replacing the DRAM storage capacitor. The SLM thus formed can be connected to a digital computer and controlled as if were a being written to as a memory, but other IC structures can also be used. In order to enhance the modulation effects, the electro-optic material is used as the spacer for a Fabry-Perot etalon structure that is also deposited on the semiconductor substrate. PLZT is a suitable electro-optic material. | ||||||
