Abstract

High efficiency coupling between semiconductor optical sources and guided wave photonic devices is a key element in achieving compact and high performance integrated photonic systems. A wide variety of materials exist in which to fabricate these guided wave components, by electro-optic (EO) polymers are rapidly emerging as the material of choice for a variety of reasons: potentially lower cost, higher speed, and greater efficiency, coupled with a flexibility of design and fabrication which is based on a spin casting technology. This greatly facilitates the hybridization of polymer devices with electronic and optoelectronic devices on a semiconductor substrate. It is the goal of this proposed research, therefore, to integrate surface-emitting horizontal cavity lasers and superluminescent diodes with electro-optic polymer waveguide devices using micromachined reflective elements (MREs). Development of this technology will result in a commercially viable integrated source/intensity modulator unit for a variety of high-speed optical data transmission applications. Further development will focus on the integration of p-l-n detectors, passive multiport couplers, and waveguide bends with immediate application to a totally integrated interferometirc fiber optic gyroscope (IFOG) chip. The semiconductor substrate will also accommodate limited analog electronics integration for detector preamplification and diode driver circuitry. All applications which employ hybrid integrated optics, i.e., multiple modules interconnected with pigtailed optical fibers, will benefit substantially from this technology: fiber sensors for physical/mechanical measurements (pressure, strain, temperature), T/R modules, fiber optic time delay networks, high speed fiber telecommunication and video networks, optically controlled phased array radar, and optical signal processing, fiber optic biosensors to detect the presence and concentration of biological and chemical contaminants, board-to-board optical interconnects for ultra high speed computer buses and low cost fiber optic gyroscopes for automobiles.
