Abstract: A system and method for facilitating passive alignment of an optical component in an optical bench. A groove is etched into the optical bench. The groove has two sections. The first section is configured to act as an optical guide. The second section is configured to receive the optical component. An optical component is inserted into the first section and moved into the second section. The optical component may be bonded to the optical bench.

Abstract: Methods of fabricating comb drive devices utilizing one or more sacrificial etch-buffers are disclosed. An illustrative fabrication method may include the steps of etching a pattern onto a wafer substrate defining one or more comb drive elements and sacrificial etch-buffers, liberating and removing one or more sacrificial etch-buffers prior to wafer bonding, bonding the etched wafer substrate to an underlying support substrate, and etching away the wafer substrate. In some embodiments, the sacrificial etch-buffers are removed after bonding the wafer to the support substrate. The sacrificial etch-buffers can be provided at one or more selective regions to provide greater uniformity in etch rate during etching. A comb drive device in accordance with an illustrative embodiment can include a number of interdigitated comb fingers each having a more uniform profile along their length and/or at their ends, producing less harmonic distortion during operation.
