Silicon Optical Bench
This allows the sidewalls of these edge locator grooves to be used in combination with the alignment bench to precisely position features on the die relative to other similarly constructed components or optical fibers.
Silicon optical bench. An optical bench or optical rail is a simpler piece of hardware that provides a linear or sometimes curved track along which to mount optical elements. Lab on a chip micropumps mems custom services. Introduction why mems for optoelectronic packaging.
The concept of a siob is the same except they use silicon with discrete optical elements such as lenses lasers mirrors or beam splitters placed into kinematic cavities or pits in the silicon designed to precisely hold each element in the correct x y and z position. For silicon optical benches hayden taylor david moore mohamed boutchich billy boyle johnny he graham mcshane richard breen rob wylie cambridge university engineering department 3 march 2004. Micralyne offers numerous application specific silicon optical bench and laser sub mount platforms to address even the most challenging cost benefit requirements.
They are often used for simple experiments especially for classroom demonstrations. Mizur technology fax 972 4 6442803 technology fax 972 4 6442803. The silicon interposer die pic die are constructed with wet etched v grooves along the locations where the die will be diced.
Groove wet etched into a silicon wafer to form an alignment bench component which can be used in combinations with silicon based interposer photonic integrated circuit pic die and either additional similar die or optical fibers assembled with cylindrical ferrules such as the lc connector ferrule. Such rails are typically made of steel and designed to be very stiff with features that allow holders for optical components to be bolted down and easily. Silicon optical benches siobs are named after the benchtop optical benches that scientists have used to study light for more than a century.
Why are siobs so useful. The silicon interposer die pic die are. Siobs are named after the benchtop apparatus optical benches used by scientists to study light phenomena for more than a century.
Silicon v groove structures have been utilized for passive positioning of optical fiber for fiber optic and opto electronic applications. In this paper we will present our results of using micro machined silicon v groove arrays to passively align optical fiber arrays to micro rod optics. High precision required.
V groove chips standard and custom silicon optical table custom substrates. As optical system architectures have matured over the past ten years the use of silicon optical bench siob technology for cost effective packaging of opto electronic components has migrated.
