Magnetorheological polydimethylsiloxane micro-optical resonator
Optics Letters, 2010We investigate the possibility of using magnetorheological polydimethylsiloxane (MR-PDMS) spheres as micro-optical resonators. In particular, the effect of a magnetic field on the whispering gallery modes (WGM) of these resonators is studied. The applied field induces mechanical deformation, causing shifts in the WGM.

Thermal Lens Micro Optical Systems
Analytical Chemistry, 2004This paper describes two types of miniaturized thermal lens optical systems that use optical fibers, SELFOC microlenses and light sources. The first system consists of a compact diode pumped solid-state laser (532 nm) as an excitation light source, a laser diode (635 nm) as a probe light source, an acoustoptic modulator as an excitation light modulator,

When used in microsystems, laser diodes are rarely found alone. The emitted light must typically be focused or collimated and directed through other optical components to perform the function for which the optical system is designed. In particular, components are required for laser beam shaping, spectral and spatial filtering, intensity and phase ...

Diamond milling of micro-optics
IEEE Aerospace and Electronic Systems Magazine, 2006A diamond mill (a tiny end mill) can cut aspheric lenses and mirrors with diameters smaller than 0.5 mm. The cutting tool has a two-dimensional shape and is spun about the axis of the surface to be cut. As the spinning tool is plunged into the substrate, it cuts a radially symmetric surface to sub-micron accuracies.

Sensors and Actuators A: Physical, 2000
An advanced optical scanner was developed with small dimensions, high-speed performance, and low power consumption. The device is well suited to fast growing applications where conventional galvano-mirrors or polygon-mirrors cannot be used due to their design limitations, over-size, or high power consumption. The advanced optical scanner, named Silicon

The process of forming cylindrical glass microlenses drawn from a precisely shaped preform provides optical engineers and designers a novel source of miniaturized optical components with very high numerical aperture and diffraction-limited performance. Because of these characteristics, and because of the inherent anamorphic nature of cylindrical optics,

Miniaturized micro-optical scanners
Optical Engineering, 1994Optical beam scanners are critical components for airborne and space-based laser radar, on-machine-inspection systems, factory automation systems, and optical communication systems. We describe here a laser beam steering system based on dithering two complementary (positive and negative) microlens arrays.
