Kaiam Corporation was an American manufacturer of optronics equipment for computer networking. Founded in 2009, it was headquartered in Newark, California, and until December 2018 had a manufacturing facility in Silicon Glen in Scotland. The CEO was Dr. Bardia Pezeshki.


Kaiam manufactured MEMS systems to link servers using optical connections.[1] The company used micromachined silicon;[2] in March 2016 it demonstrated the CWDM4, a 100 Gigabit-per-second coarse wavelength division multiplexing (CWDM) silicon photonics transceiver using silicon modules and receivers.[3]


The company was founded in 2009[4] by Pezeshki, an Iranian native[5] who had previously founded Santur Corporation.[6] It initially produced TOSA/ROSAs (transmitter optical subassemblies and receiver optical subassemblies).[7]

In April 2013 it acquired Gemfire Corp.,[8] and in 2014, with a grant from Scottish Enterprise, moved production from China to Gemfire's wafer fabrication plant in Livingston, West Lothian,[5][9][10] which had been built in the late 1990s by Kymata, a company spun off from research at Glasgow University and Southampton University, to produce photonic integrated circuits.[1] Pezeshki relocated to Edinburgh in 2015 to explore moving the company's research and development program to Scotland.[1] At the plant Kaiam produced integrated optical components on a 200mm-diameter wafer silica-on-silicon line, and also 40Gb/s and 100Gb/s optical packaging products.[11]

In April 2017, Kaiam bought a wafer fabrication facility in Newton Aycliffe in England from Compound Photonics Group;[11] it resold the plant to II-VI Inc. in August that year.[12][13] In May 2018, the company signed a memorandum of understanding with Broadex Technologies Co. for co-manufacturing of transceivers based on its LightScale2 platform for the Chinese market.[14]

The company was unable to secure enough orders to sustain full production at its facility in Scotland, and was seeking a financial partner in December 2018.[15] Shortly before Christmas, 310 workers at the plant were laid off with no notice and before receiving their end of year pay.[10][16] Companies House had issued a striking-off order on November 27.[17][18] Pezeshki visited the plant immediately before workers were informed that the factory would be closed until January 3;[9][13][17] the company's subsidiaries Kaiam Europe Limited and Kaiam UK Limited were placed in administration.[13][19] The redundancies were then made permanent on Christmas Eve; 28 employees were retained to assist with selling the plant.[20][21] Crowdfunding and in-kind donations were organized to assist those laid off.[13][17][18][22][23] In March 2019, the plant was sold to Broadex.[24]

Kaiam was sued for patent infringement by Finisar, following which the company collapsed in early 2019.[25] In January, Kaiam made a general assignment for the benefit of its creditors; in May, an agreement was reached under which Finisar accepted an unsecured claim on Kaiam's estate as satisfaction of a $10 million judgment.[26]
