Tunable optoelectronic devices.
Mateus, Carlos Fernando Rondina.

Tunable optoelectronic devices. - 217 p.

Chair: Constance J. Chang-Hasnain.

Thesis (Ph.D.)--University of California, Berkeley, 2004.

Design is described in separate for optical cavity and mechanical beams. A novel grating mirror, with both high bandwidth and reflectivity, is theoretically and experimentally demonstrated as an alternative to the conventional distributed Bragg reflectors. General design rules and scaling laws with wavelength are presented in a flowchart as function of system requirements such as tuning range, central wavelength, tuning voltage, tuning speed and resolution. By following the various steps, all mechanical and optical parameters are derived.

520 # $a Design is described in separate for optical cavity and mechanical beams. A novel grating mirror, with both high bandwidth and reflectivity, is theoretically and experimentally demonstrated as an alternative to the conventional distributed Bragg reflectors. General design rules and scaling laws with wavelength are presented in a flowchart as function of system requirements such as tuning range, central wavelength, tuning voltage, tuning speed and resolution. By following the various steps, all mechanical and optical parameters are derived.
520 # $a This dissertation discusses design, fabrication and applications of monolithically tuned optoelectronic devices. The devices have vertical optical cavity with respect to the substrate, which uses micro-machining techniques to provide the largest monolithic tuning range among all options.
520 # $a Tunable detector and laser were used to develop a compact label-free biosensor. The laser approach has demonstrated to be more attractive and it was integrated to a guided mode resonant (GMR) filter in order to compose the label-free system. The GMR has spectral characteristics strongly dependent on optical thickness on its surface and this dependence can be directly correlated to interactions among proteins. The tunable devices allow the identification of spectral changes on the GMR and can replace a spectrometer, enabling compactness and enhancing sensitivity. The sensor has sensitivity of detecting antigen concentration as low as 1pg/ml (6.7 femto-Molar) and is also suitable for measuring both static and dynamic interaction among proteins.
520 # $a Tunable devices, specifically filter, detector and laser, are key components for a variety of applications such as communications, spectroscopy, biosensing, inter and intra-chip connection, infrared (IR) imaging, and biometrics. Monolithically tuned devices are even more attractive because of compactness, robustness, easiness of integration, and low price inherent to semiconductor batch fabrication and testing.
520 # $a Tunable filters with novel designs were developed for applications in communications and IR imaging. The first development uses a torsional structure, which provides extended tuning and avoids catastrophic discharges, to establish a record tuning range (>100nm) around 1.55mum. The second uses folded beams to increase the surface area coverage, enabling 2D arrays of such devices to be integrated to focal plane arrays in the middle (3--5mum) and long (8--12mum) IR spectra.
