Tunable insertion of multiple lines into a Kerr frequency comb using electro-optical modulators

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Yan Yan, Lin Zhang, Ahmad Fallahpour, Amirhossein Mohajerin Ariaei, Cong Liu

We experimentally insert a flexible number of electro-optical (EO) comb lines into a Kerr frequency comb via EO modulation and demonstrate the use of combined Kerr and EO combs as light sources in coherent communications. The number of EO lines inserted in ...

Imaging blood cells through scattering biological tissue using speckle scanning microscopy

Demetri Psaltis, Ye Pu, Xin Yang

We demonstrate imaging of blood cells enclosed in chicken skin tissue using speckle scanning microscopy (SSM). Clear images of multiple cells were obtained with subcellular resolution and good image fidelity, provided that the object dimension was smaller ...

Bandwidth and repetition rate programmable Nyquist sinc-shaped pulse train source based on intensity modulators and four-wave mixing

Camille Sophie Brès, Mohammad Amin Shoaie, Steevy Joyce Cordette

We propose and experimentally demonstrate an all-optical Nyquist sinc-shaped pulse train source based on intensity modulation and four-wave mixing. The proposed scheme allows for the tunability of the bandwidth and the full flexibility of the repetition ra ...

Optical characterization of two-dimensional array of 2048 tilting micromirrors for astronomical spectroscopy

Nico de Rooij, Michael David Canonica, Wilfried Noell

A micromirror array composed of 2048 silicon micromirrors measuring 200 x 100 mu m(2) and tilting by 25 degrees was developed as a reconfigurable slit mask for multi-object spectroscopy (MOS) in astronomy. The fill factor, contrast, and mirror deformation ...

Monte Carlo simulation of the field back-scattered from rough surfaces

Christian Depeursinge, Yves Delacrétaz, Stéphane Chamot

A novel approach for the simulation of the field back-scattered from a rough surface is presented. It takes into account polarization and multiple scattering events on the surface, as well as diffraction effects. The validity and usefulness of this simulat ...

Optofluidic lock-in spectroscopy on a chip

Demetri Psaltis, Wuzhou Song

We introduce for the first time the implementation of optofluidic lock-in spectroscopy of sub-nanoliter analyte on a microfluidic chip. Two methods, spatial modulation and pneumatic modulation with integrated optofluidic modulator, were demonstrated. (C) 2 ...

Tuning Mechanisms in Optofluidics

Demetri Psaltis, Wuzhou Song, Jae-Woo Choi

Novel functionalities have been developed through the fusion of optics and microfluidics. We categorize the different possible tuning mechanisms in optofluidics and describe the recent examples in each category. (C)2010 Optical Society of America ...

Inline holographic coherent anti-Stokes Raman microscopy

Demetri Psaltis, Ho Ling Li, Kun Shi

We demonstrate a simple approach for inline holographic coherent anti-Stokes Raman scattering (CARS) microscopy, in which a layer of uniform nonlinear medium is placed in front of a specimen to be imaged. The reference wave created by four-wave mixing in t ...
