Modulating Short Wavelength Fluorescence with Long Wavelength Light

Journal of the American Chemical Society, 2014
Two molecules in which the intensity of shorter-wavelength fluorescence from a strong fluorophore is modulated by longer-wavelength irradiation of an attached merocyanine-spirooxazine reverse photochromic moiety have been synthesized and studied. This unusual fluorescence behavior is the result of quenching of fluorophore fluorescence by the thermally ...

Laser Wavelength Selection

Applied Optics, 1968
The advent of multiwavelength lasers has stimulated considerable interest in wavelength selection, i.e., methods of selecting for various applications one or more of the available wavelengths from a given laser. This paper describes a technique for parallel wavelength separation or recombination of laser beams external to laser cavities.

Behavior of distributed wavelength provisioning in wavelength-routed networks with partial wavelength conversion

IEEE INFOCOM 2003. Twenty-second Annual Joint Conference of the IEEE Computer and Communications Societies (IEEE Cat. No.03CH37428), 2004
Distributed wavelength provisioning is becoming one of the most important technologies for supporting the next-generation wavelength-routed networks. In this paper we analyze the behavior of wavelength-routed networks with partial wavelength conversion capabilities (i.e., where wavelength conversion is available at only a subset of network nodes) when ...

Dual-wavelength phase-shifting digital holography selectively extracting wavelength information from wavelength-multiplexed holograms

Optics Letters, 2015
Dual-wavelength phase-shifting digital holography that selectively extracts wavelength information from five wavelength-multiplexed holograms is presented. Specific phase shifts for respective wavelengths are introduced to remove the crosstalk components and extract only the object wave at the desired wavelength from the holograms.

Two-Wavelength Interferometry

Applied Optics, 1973
Previous methods of two-wavelength variable-sensitivity interferometry are reviewed and a simplified two-wavelength technique for interferometric testing under static conditions is discussed. An extension of the static technique to real-time dynamic testing is proposed and an operational variable-sensitivity interferometer utilizing the real-time ...

Wavelength Reservation in Wavelength-routed Optical Networks

Journal of Optical Communications, 2006
A novel wavelength reservation protocol is proposed for wavelength-continuous lightpaths establishment in the wavelength-routed optical networks. The protocol uses backward reservation protocol (BRP) with intermediate retry to reduce the chance of blocking.

Wavelength-selective photodetectors operating at long wavelength

SPIE Proceedings, 2006
We demonstrate a wavelength-selective photodetector that combines a Fabry-Perot filtering-cavity (FPC) with a taper absorption-cavity (TAC). The taper cavity shows non-resonant effect but exhibits absorption enhancement effect, so that high-speed, high quantum efficiency, wide tuning range and ultra-narrow spectral linewidth can be achieved ...

Wavelength requirements in wavelength-routed ring networks

Fifth Asia-Pacific Conference on ... and Fourth Optoelectronics and Communications Conference on Communications,, 1999
In this paper, we discuss the wavelength requirements for wavelength-routed ring networks. A new integer linear programming (ILP) formulation is proposed for routing and wavelength assignment of wavelength path (WP) and virtual wavelength path (VWP) routing schemes.
