In this dissertation, a fabrication process for PFCB waveguide air-trench bends on top of silicon substrate with electron beam lithography (EBL) and autoalignment has been developed and a high efficiency air-trench bend (9. % for TE polarization and 9. % for TM polarization) has been demonstrated.

The use of polymer waveguides for the design and fabrication of devices for wavelength division multiplexing (WDM) at 1550 nm is described. Single mode 1 X 2, 1 X 4 and 1 X 8 splitters and combiners have been fabricated using photosensitive polyimide materials on silicon substrates. Good division of light was achieved in the devices, and waveguide facets could be cleaved to allow efficient coupling from optical fibers. The design of phased array wavelength demultiplexers for polymer waveguide technologies is described and compared to competitive technologies.

This novel series of PFCB polymers exhibits low optical attenuation, high thermal stability, and tailorable refractive index, facilitating the design of high-performance photonic devices. The design, fabrication, and characterization of AWGs are reported in this pape. ONTINUE READING.

In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (. colors) of laser light. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity.

The photolithography defined polymeric waveguides enable us to fabricate a 10-meter long optical channel waveguide circuit with sub-micron accuracy in a five-inch silicon wafer, providing optical true-time-delays over tens of nanoseconds with sub-picosecond time resolution. The unique detector-switched operation achieves a nanosecond switching time over 60 GHz bandwidth

A fabrication process for PFCB waveguide air-trench bends on silicon substrate with electron beam lithography (EBL) and autoalignment has been developed and a high efficiency air-trench bend (97.2% for TE polarization and 96.2% for TM polarization) has been demonstrated. The simulation predicts an optical efficiency of 98.5% for TE and 98.2% for TM when the Goos Hanchen shift is properly accounted for. We have adapted this process to making air trench bends in PFCB waveguides on polyimide substrates. Compared to silicon substrates, the polyimide substrates have the advantage of less coefficient of thermal expansion (CTE) mismatch with PFCB films, which improves fabrication repeatability and yield. Using air-trench bends, an ultracompact 8 x 8 arrayed waveguide grating (AWG) demultiplexer (200 GHz) for WDM has been designed and fabricated on a polyimide substrate. Compared to a conventional AWG in the same material system, the air-trench bend AWG shrinks the required chip area by a factor of 20. The decreased size is a factor in reducing the measured thermal shift to -0.012 nm/C and decreasing the polarization-dependent wavelength shift to 1.3 nm.
