About Us

Spectralus Corporation was founded in 2003 by Dr. Stepan Essaian with the mission to develop high-efficiency, mass-manufacturable, periodically-poled nonlinear optical crystals and laser products enabled by these crystals.

Dr. Stepan Essaian is President, CEO, and Founder of Spectralus. He has over 20 years of technical and management experience in solid-state optoelectronics, semiconductor devices, and telecommunications systems and networks. In 2000-02, Dr. Essaian served as the Chief Scientist for Solid State Photonix/Teraburst Networks Co, a leading developer of an OMO analog switch for OXCs. At Teraburst, Dr. Essaian has directed the development of advanced all-optical switch devices for future OXC systems.

Prior to working at SSP, Dr Essaian was staff member of CMOS and SiGe processing research and development group at National Semiconductor Co. Before National Semiconductor, he was a Visiting Professor at the Materials Science Department of Rutgers University. Before immigration to the US, Dr. Essaian was a Principal Scientist at Ioffe Physico-Technical Institute in St Petersburg, Russia, and Professor of Optics at Yerevan State University, Armenia, where worked in the fields of acousto-optics, electro-optics, and photo-refractive effects and nonlinear-optics effects in dielectrics and semiconductor materials.

Dr. Essaian is an author of over 100 publications. He holds 12 patents in the field of advanced materials and processes and optical-related technologies. In addition, he has 5 pending patent applications on PPLN technology. Dr. Essaian holds an D.Sc. and Ph.D in Solid State Physics and Optoelectronics from Ioffe Physico-Technical Institute, St. Petersburg (Russia)

In 2008 to 2009, the company refocused on developing high-efficiency, ultra-compact green laser sources primarily for mobile projection applications. This development program specifically resulted in the miniature ATTO green laser that became available to customers in early 2010.  This device offers industry-leading power conversion efficiency, from a robust, reliable package specifically designed for incorporation as the green light source within picoprojectors. 

The primary crystal in the current product portfolio is periodically-poled, MgO-doped lithium niobate (PPMgOLN). Over the last several years, the company has further developed and fine-tuned the manufacturing of this engineered nonlinear crystal.  It is used for high-efficiency nonlinear conversion of laser sources (most commonly, near-infrared) into more desirable wavelengths such as blue, green and yellow (400 to 600nm) via a second-harmonic generation process and to mid-IR via DFG or OPO processes. These PPMgOLN elements are well-suited for high-quality and cost-effective applications in instrumentation, laser displays, biomedical, scientific, and other laser markets.

The company is now expanding its efforts to deploy these lasers more broadly in projection-based applications via increasing the number of versions available.  It is also extending the green laser platform for use in other applications such as biomedical and analytical instrumentation, industrial and government areas.  Spectralus is interested both in simply providing green lasers to the market, as well as partnering closely with customers who may want to develop a specific laser version under their own auspices.

Spectralus’ headquarters are located in Santa Clara, CA (USA), within “Silicon Valley”. 
A production facility subsidiary is located in Yerevan, Armenia.
