Invited Article: Optical dynamic range compression

open access: yesAPL Photonics, 2018
We introduce the concept of optical dynamic range compression and discuss its utilities in the non-uniform quantization, enhancing the signal-to-noise ratio as well as reshaping signal’s statistical distribution and extending the detection range in light

Invited Article: Bragg stacks with tailored disorder create brilliant whiteness

open access: yesAPL Photonics, 2018
The scales of white beetles strongly scatter light within a thin disordered network of chitin filaments. There is no comparable artificial material achieving such a high scattering strength within a thin layer of low refractive index material.

Invited Article: A compact optically coherent fiber frequency comb [PDF]

open access: bronzeReview of Scientific Instruments, 2015
We describe the design, fabrication, and performance of a self-referenced, optically coherent frequency comb. The system robustness is derived from a combination of an optics package based on polarization-maintaining fiber, saturable absorbers for mode ...

Invited Article: Chiral optics of helicoidal cellulose nanocrystal films

open access: yesAPL Photonics, 2017
Cellulose nanocrystals in water suspensions behave as lyotropic liquid crystals forming a chiral nematic phase above a critical concentration. Such an organization can be retained in solid films and give rise to an intense
