Designing coupled-resonator optical waveguide delay lines [PDF]
, 2004 We address the trade-offs among delay, loss, and bandwidth in the design of coupled-resonator optical waveguide (CROW) delay lines. We begin by showing the convergence of the transfer matrix, tight-binding, and time domain formalisms in the theoretical ...

Continuously tunable ultra-thin silicon waveguide optical delay line
, 2017 As light cannot be stopped or directly stored in any media, optical delay lines are usually used to temporally trap the optical signals. We report a wide-range continuously tunable optical delay line chip consisting of a ring resonator array and a Mach ...

A digital delay locked loop with a monotonic delay line
Electronics Letters, 2023 This paper proposes a digital delay locked loop (DLL) with a monotonic delay line (DL). This DLL adopts the calibration mode to reduce the non‐monotonic effects for the coarse‐tuning delay line (CTDL) and the fine‐tuning delay line (FTDL).

Geometric Scattering in Robotic Telemanipulation [PDF]
, 2002 In this paper, we study the interconnection of two robots, which are modeled as port-controlled Hamiltonian systems through a transmission line with time delay. There will be no analysis of the time delay, but its presence justifies the use of scattering

Equivalence of Open-Loop and Closed-Loop Operation of SAW Resonators and Delay Lines
Sensors, 2019 Surface acoustic wave (SAW) sensors in the form of two-port resonators or delay lines are widely used in various fields of application. The readout of such sensors is achieved by electronic systems operating either in an open-loop or in a closed-loop ...

A Multi-Moded RF Delay Line Distribution System for the Next Linear Collider
, 2002 The Delay Line Distribution System (DLDS) is an alternative to conventional pulse compression, which enhances the peak power of rf sources while matching the long pulse of those sources to the shorter filling time of accelerator structures. We present an
