The delay lines for the Magdalena Ridge Observatory Interferometer in New Mexico are required to provide up to 380m optical path delay with an OPD jitter of better than 15nm, in vacuum, using a single adjustable stroke. In order to meet these demanding requirements in a cost-effective manner a unique combination of techniques has been used in the design and construction of the delay line trolle...

We introduce the concept of an indirect photonic transition and demonstrate its use in a dynamic delay line to alter the group velocity of an optical pulse. Operating on an ultrafast time scale, we show continuously tunable delays of up to 20 ps, using a slow light photonic crystal waveguide only 300 μm in length. Our approach is flexible, in that individual pulses in a pulse stream can be cont...

Optical burst switching networks have received a lot of attention in the research community in the recent years. The JET protocol, first proposed by Qiao and Yoo in 1997 in [6, 5], is used for resource allocation in these networks. Up to the present, the JET protocol has been studied in networks that use wavelength conversion [7, 1]. In this paper the JET protocol is discussed in optical networ...

The extremely high data rates of optical computing technology (100 MWords per second and upwards) present unprecedented challenges in the dynamic memory design. An optical ber loop, used as a delay line, is the best candidate for primary, dynamic memory at this time. However, they pose special problems in the design of algorithms due to synchronization requirements between the loop data and the...

The implementation of fiber-optic lattice structures incorporating single-mode fibers and directional couplers was presented by Behzad Moslehi et al (1984). These fiber structures can be used to perform various high-speed time domain and frequency domain functions such as matrix operations and frequency filtering. They introduce the concept of lattice structure optical filters. Lattice structur...
