DPH mode selectors improve laser beam quality

DPH mode selectors were successfully tested with a multi-mode semiconductor laser in October of 2009. Inserting the DPH mode selector into the cavity as an output mirror decreased the number of transverse modes from 10 to 1, beam divergence from 20 to 4.8 degrees, and the laser spectral width from 4 to 0.4 nm. Experiments to be continued for optimizing the mode selector configuration and coupling. In parallel, the monolithic design of lasers with DPH components (mode selectors or beam combiners) is being considered.

Nano-Optic Devices announces that it develops a visible-NIR spectrometer for Russian Mars missions

It will be the first digital spectrometer, targeting only selected spectral lines. The agreement between Nano-Optic Devices and the Institute of Space Research of Russian Academy of Sciences has been signed.

Ten-mm-long nano-spectroscope with spectral spacing 0.015nm

In September of 2008 several nano-spectroscopes for the visible band with spectral channel spacing up to 0.015 nm were fabricated and successfully tested. This is an important milestone for Nano-Optic Devices and its unique Digital Planar Holography (DPH) technology. The devices are micro-lithographically produced on small chips (10 x 5 x 1 mm³ each). Commercially available conventional spectroscopes of the same resolution are several orders of magnitude larger and heavier. New high-resolution devices can be used for Raman spectrometry, laser wavelength monitoring and stabilization, and other applications. This result opens new ways in the development of planar integrated lightwave circuits and confirms the great potential of the disruptive DPH technology.

A new NOD office was opened in August of 2008 in Santa Clara, CA.

NOD organized in 2008 three Workshops on DPH Technology and Applications:

Workshop II was held in San Francisco, California on May 7-9. The program included 10 presentations on various aspects of the DPH and its applications. The participants discussed ways of improving DPH-devices, new areas of application for them, and approaches to Technology commercialization. Action items were discussed and formulated.

Workshop III was held in Troitsk, Russia on June 1-3. It was dedicated to design and testing of DPH-devices and included 8 technical presentations. After fruitful discussions new milestones of DPH development were determined.

Workshop IV was held in the NOD California office on October 10-11. The agenda included fabrication, design, and testing of DPH-devices as well as discussion of prospective applications and included 7 technical presentations. Additional directions for DPH development were proposed and discussed.
