OSSC 2019 - 2020 Election

The elections are open for 2019-2020 Programs Year.
Dear OSSC Member,
The Board of Directors and Nominating Committee of the Optical Society of Southern California are pleased to provide the 2019-2020 election materials including candidate photos and biographies to help you chose whom to elect.  Each of the individuals running for office has agreed to serve the Society in some capacity next year in either an elected or appointed position.  Their involvement is welcome and appreciated.  Members have the option of voting online or requesting a mail-in ballot.  Members must log-in to vote; contact the Membership Chair or Webmaster if you need assistance.  On-line voting is anonymous, secure and the best way to ensure that your vote is counted.  On-line voting will close Wednesday June 12 at noon.  Paper ballots must be received before the June 12 meeting.  If you vote by mail, please send it in right away.  You may also turn in the ballot in person at the June meeting before 7:00PM.
The election results will be announced at the 12 June, 2019 OSSC meeting at Brea Civic Center, 1 Civic Center Circle, Brea, CA 92821.  The meeting announcement is included herein. The June meeting includes our annual OSSC Business Meeting and announcement of next years officers who will serve from 1 July, 2019 to 30 June, 2020.  Meeting reservations may be made on-line at or by contacting the Arrangements Chair.  It has been a tremendous honor and pleasure serving as President of the Society this past year.  I look forward to assisting our next President and the entire new Board of Directors and look forward to serving this great organization for many years.
Nicholas J Croglio Jr.
OSSC President, 2018-2019

Upcoming OSSC Meeting

Wednesday 12 June
Annual Business Meeting & Election Results
and talk on:
Quantum Computing &
The National Quantum Initiative

Abstract:  Quantum computing is the use of quantum-mechanical phenomena such as superposition and entanglement to perform computation.  A quantum computer is used to perform such computation, which can be implemented theoretically or physically.
The National Quantum Initiative (NQI) Act is an Act of Congress passed on December 13, 2018 and signed into law on December 21, 2018.  The law gives the United States a plan for advancing quantum technology, particularly quantum computing.  OSSC Fellow Donn Silberman will briefly review the NQI and introduce our speakers.
Visit to explore these topics prior to the meeting.
Networking, Social Hour:  6:00
Dinner:  6:30
(Members:  $35 by 7 June, $40 after,
Non-Members:  $40 by 7 June, $45 after,
OSSC Student Members:  $10 by 7 June, $20 after)

Recent OSSC Meeting

Wednesday 8 May

Abstract:  Multi-layer optical coatings play a key part in modern photonics, tailoring optical properties to create high-performance mirrors, low reflectivity surfaces, and wavelength or polarization dependent optics.  Without such coatings, many optical systems would not be practical, or even possible.  While multi-layer optical coating technology has developed tremendously since its inception in the 1940’s, there are still challenges that can lead to failed designs and require optimization by trial and error.
Much of the trial and error in coating design is driven by the difficulty in accurately specifying index dispersion for each material.  While index dispersion can be approximated by bulk index values or thin film measured values, for many this is insufficient to accurately design a coating without multiple iterations.  What is required is an accurate estimate of index dispersion produced by a particular coating technique on a particular machine.
The IDEM system provides a unique index calibration for each material and process used in particular machine.  IDEM then monitors the reflected vis/NIR spectrum (400nm-900nm), fitting the reflectivity curve derived for the layer’s calibrated index dispersion and the combined dispersion of the substrate and previous layers (IDEM can track more than four layers on one witness chip), rather than monitoring a key wavelength.  Additional benefits are continuous insight into system performance, and ability to restart a coating run after a system interruption.  IDEM significantly increases the reliability and efficiency of creating multi-layer optical coatings, reducing lead-time and increasing cost margin.

Recent VOSA Meeting

Tuesday 14 May
Using Optics and Precision Metrology in LIGO to Measure Black Hole Mergers from Across the Universe
VOSA 190514
Dr. Joshua R. Smith,
Dan Black Director of Gravitational Wave
Physics and Astronomy
Cal State University, Fullerton
Abstract:  In 2015, the two detectors of the Laser Interferometer Gravitational Wave Observatory (LIGO) detected gravitational waves from the coalescence of a binary system of black holes.  This discovery could not have been made without a century of advances in optical technology and precision metrology.  An overview of gravitational waves and LIGO will be given describe the optics involved and current optical challenges, discuss the discovery of gravitational waves from merging black holes and neutron stars and end with how optical technology is being used to prepare for the next-generation of gravitational-wave observatories..
