About Me:

PhD Graduation (May 2020), University of New Mexico, Albuquerque, NM

Optical scientist and engineer experienced in design and development of optical, electro-optical, and laser systems. Extensive hands-on experience in nonlinear optics (OPO), solid-state lasers (Yb, Tm, and Ho-doped), fiber amplifiers, optical alignment and laser frequency stabilization, optical system design (Zemax, RSoft), metrology, high vacuum systems, cryogenic fluorescence spectroscopy, and material characterization. Knowledgeable in mathematical modeling, image processing, data acquisition and analysis, and instrument control (MATLAB, LabVIEW).
Job experience as an optical engineer at an ISO holding laboratory to perform standard optical tests on various passive and active electro-optical components in DWDM technology.

Work Experience:

I worked as an optical engineer at Active Optical Devices Laboratory (AODL) at Laser and Plasma Research Institute at Shahid Beheshti University in Iran. This lab is an accredited type approval laboratory for testing optical communication devices. I have been performing tests (listed below) and creating test reports according to ISO 1725 standard on various active and passive optical components:

Preparing a type approval laboratory according to ISO/IEC 17025 standard
Performing standard tests for agents of accreditation bodies
Optical loss, gain and dispersion tests on active and passive devices
SDH/SONET, BERT, Jitter/Wander, and Environmental Tests
Test Equipment: JDSU MAP modules, OSA and OTDR, Anritsu eye-pattern analyzer, SWS, Fujikura (SM, MM, PM) fiber splicers, Temperature and humidity controlled chambers, fiber polishing, inspection and connectorizing.
