Recent Developments in UV Optics for Ultra-Short, Ultra-Intense Coherent Light Sources

open access: yesPhotonics, 2015
With the advent of Free Electron Lasers and general UV ultra-short, ultra-intense sources, optics needed to transport such radiation have evolved significantly to standard UV optics.

Ion-Exchanged Glass Waveguide Technology: A Review [PDF]

open access: yes, 2011
We review the history and current status of ion exchanged glass waveguide technology. The background of ion exchange in glass and key developments in the first years of research are briefly described.

ACTIVE OPTICAL CLOCKS

open access: yesFrequency Standards and Metrology, 2009
This letter presents the principles and techniques of active optical clock, a special laser combining the laser physics of one-atom laser, bad-cavity gas laser, super-cavity stabilized laser and optical atomic clock. As an example, a compact version of active optical clock based on thermal Strontium atomic beam shows a quantum-limited linewidth of 0.51

Magnetoplasmonic design rules for active magneto-optics

open access: yes, 2014
Light polarization rotators and non-reciprocal optical isolators are essential building blocks in photonics technology. These macroscopic passive devices are commonly based on magneto-optical Faraday and Kerr polarization rotation.

Diamond electro-optomechanical resonators integrated in nanophotonic circuits [PDF]

open access: yes, 2014
Diamond integrated photonic devices are promising candidates for emerging applications in nanophotonics and quantum optics. Here we demonstrate active modulation of diamond nanophotonic circuits by exploiting mechanical degrees of freedom in free ...

Discrete solitons in coupled active lasing cavities [PDF]

open access: yes, 2012
We examine the existence and stability of discrete spatial solitons in coupled nonlinear lasing cavities (waveguide resonators), addressing the case of active defocusing media, where the gain exceeds damping in the low-amplitude limit.

Thin-disk laser pump schemes for large number of passes and moderate pump source quality

open access: yes, 2015
Novel thin-disk laser pump layouts are proposed yielding an increased number of passes for a given pump module size and pump source quality. These novel layouts result from a general scheme which bases on merging two simpler pump optics arrangements ...

Two-level laser light statistics [PDF]

open access: yes, 2002
The statistics of the light emitted by two-level lasers is evaluated on the basis of generalized rate equations. According to that approach, all fluctuations are interpreted as being caused by the jumps that occur in active and detecting atoms. The intra-

Optically Activated Delayed Fluorescence [PDF]

open access: yesThe Journal of Physical Chemistry Letters, 2017
We harness the photophysics of few-atom silver nanoclusters to create the first fluorophores capable of optically activated delayed fluorescence (OADF). In analogy with thermally activated delayed fluorescence, often resulting from oxygen- or collision-activated reverse intersystem crossing from triplet levels, this optically controllable/reactivated ...
