Delay Line as a Chemical Reaction Network [PDF]
Parallel Processing Letters, 2015 Chemistry as an unconventional computing medium presently lacks a systematic approach to gather, store, and sort data over time. To build more complicated systems in chemistries, the ability to look at data in the past would be a valuable tool to perform

Resonant Graphene-Based Tunable Optical Delay Line
IEEE Photonics Journal, 2015 The design of a new graphene-based continuously tunable optical delay line formed by two vertically stacked microring resonators coupled to a straight waveguide is proposed. High values of delay time (τg = 360 ps) and a wide tuning range (Δ&

Subwavelength grating enabled on-chip ultra-compact optical true time delay line. [PDF]
Sci Rep, 2016 An optical true time delay line (OTTDL) is a basic photonic building block that enables many microwave photonic and optical processing operations. The conventional design for an integrated OTTDL that is based on spatial diversity uses a length-variable ...

Reservoir Computing Using a Spin-Wave Delay-Line Active-Ring Resonator Based on Yttrium-Iron-Garnet Film [PDF]
Physical Review Applied, 2019 The authors demonstrate the use of a propagating spin waves for implementing a reservoir computing architecture. The proposed concept utilises an active ring resonator comprising a magnetic thin film delay line integrated into a feedback loop.

Amplification of optical delay by use of matched linearly chirped fiber Bragg gratings [PDF]
, 2004 We describe the use of a matched linearly chirped fiber Bragg grating (FBG) pair as a key element in an adjustable optical delay line. This delay line has the unique property that the achievable optical group delay is orders of magnitude greater (factor ...
