Surface-micromachining technology offers many advantages for implementing optical MEMS. It is versatile; many different types of optical MEMS devices can be fabricated by the same process. This enables monolithic integration of an entire free-space optical system onto a single chip.

Optical switches are desirable for reconfiguring the fibre-optics networks because of the very low insertion loss and high isolation requirements. Most conventional fibre-optic switches are made in-waveguide, which results in high coupling loss. A free-space approach allows a low coupling loss and small crosstalk. Recently, there has been a growing interest in applying the MEMS technology to improve the performance and reduce the cost of optomechanical switches. The novel 4/spl times/4 free-space fiber-optic switch reported can be made compact and lightweight, and is potentially integrable with optical source/detector and controlling electronic devices.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

We present a pictorial portfolio of various 2 and 3 dimensional crystal structures which have been conceived, and indicate the applications, such as opto-electronic devices. In photonic crystals there can be localized electromagnetic modes that result from \"donor\" defects, and \"acceptor\" defects in the periodic structure. The frequencies of these localized modes is sensitively controlled by the exact position of a very tiny dielectric \"impurity\". Thus photonic crystals can be exquisitely sensitive to very small motions or movements of a very tiny amount of dielectric material. This may translate to a very high speed of MEM's modulation speed of the photonic crystal switching properties. In addition, due to the inherent miniaturization of photonic crystals, a high level of complexity can be accommodated, allowing for example, large, high speed switchable arrays.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

Using VLSI fabrication processes such as photolithography, film deposition and etching, it is possible to obtain sub-micrometer-precision structures in a large quantity with excellent alignment between each other. In addition, movable structures such as micro gears and motors can be made by surface micromachining processes. Precise V-grooves and moles going through the substrate can be etched bp dry and wet etching. Such micromachining technologies have the following implications for optical systems: integration of devices; accurate pre/passive alignment; feature size comparable to wavelength; arrayed and repetitive structures; wavelength independence; free-space optics with short propagation path; high sensitivity and fast response; local servo feedback; hermetic/vacuum packaging. Examples of these implications are given for a pigtailed silicon platform for integrating optical fibres and micromachined devices, and a 2D micro-optical scanner.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

Several applications of microelectromechanical systems (MEMS) require handling of large optical powers.

Among them, monolithically integrated optical devices show strong potential for small-size, high-density applications. The integrated optical devices require optical interconnections between movable (e.g. pickup) and stationary optical components (e.g. light source and detector). Conventional optical interconnection has been made by fiber-optic cables or waveguide channels on a flexible ribbon. In this paper, we propose a free-standing (or suspended) waveguide as a new optomechanical interconnection, that can act not only as an optical path but also as a mechanical suspension for an integrated optical device. This has motivated the study on the mechanical behavior and the optical characteristics of the free-standing waveguide. We experimentally characterize the micromechanical behavior and the optical loss of a mechanically deflected free-standing polymer waveguide. We especially focus on the evaluation of the waveguide bending loss, generated by mechanical deflection.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.
