10/16/2019: C. Bigler et al., “Holographic Waveguide HUD with in-line pupil expansion and 2D FOV expansion“, accepted for publication in Applied Optics, to appear in the Special issue on Digital Holography and 3-D Imaging, Vol.58, G326-G331 (2019). Link
In this publication, we present an head up display with expanded pupil using a waveguide and holograms. The geometry of the system is in-line instead of L shaped, which bring some benefits.

In this article we present a potential solution to the limited steering angle of phase array LIDAR due to large (compared to wavelength) pixel size.
09/17/2019: I will be attending the OSA conference “Frontier in Optics” in Washington DC, and will be participating to the Facebook’s “Augmented Reality Optics & Display” Academic Forum. Link
09/18/2019: During the FiO conference, I will be organizing a networking session on behalf of the Holography and Diffractive Optics Technical Group. The theme of the session will be “must AR headsets reproduce accommodation?“. Link

In collaboration with UC Berkeley, we designed a phase modulation MEMS for optical beam steering. This new type of MEMS is fast and efficient, and can be useful for LIDAR or optical switch for data center.
05/19/2019: I will be attending the OSA Digital Holography Conference in Bordeaux, France. Link
I will be presenting the following 4 papers:
I will also be panelist for the OSA holography technical group event: “The next scientific contributions of Holography”, taking place Monday May 20th during lunch time.
04/11/2019: P.-A. Blanche and B. Lynn: “Diffraction-Based light beam scanner” Patent US 2019/0107711 A1. Link
This patent is about how to use a spatial light modulator to steer a light beam and compensate for the chromatic aberration in a monostatic LIDAR configuration.
