Waveguide Components

open access: yes, 2022
Waveguide components such as waveguides as transmission lines, mode transducers, terminations, discontinuities, attenuators, phase shifters, multiport junctions, directional couplers, filters, diplexers, and multiplexers are extensively employed in ...

Parallel Vector Processing in Optical Computing With Jacobi Time‐Wave Packets

open access: yesLaser &Photonics Reviews, EarlyView.
Functionality of a single neuron and state of the art photonic acceleration with a Mach‐Zehnder‐interferometer (MZI) mesh (i), a crossbar array (ii) and a micro ring resonator (MRR) array (iii). In the proposed Jacobi time‐wave packet approach (iv) a single modulator (here a ring modulator) is performing the whole scalar vector product in a single ...

SPECTRAL APPROACH TO ESTIMATION OF REFLECTION RESONANCES IN A RECTANGULAR WAVEGUIDE WITH A RECTANGULAR POST

open access: yesRadio Physics and Radio Astronomy, 2014
Revealing the physical phenomena causing various resonant phenomena is a key to successful design of frequency selective structures. Within the frames of the spectral theory of open waveguide resonators, the nature of the total reflection resonance ...

Dual‐Metasurface‐Integrated Fiber Array for Bidirectional Cylindrical‐Vector‐Beam Multiplexed Communication Using Off‐Axis Spatial Manipulation

open access: yesLaser &Photonics Reviews, EarlyView.
A dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...

Empty Substrate Integrated Waveguide Coupler and Transition Structure to WR-3 Waveguide

open access: yesIEEE Access
This paper proposes a sub-THz Riblet coupler based on the empty substrate integrated waveguide (ESIW) and a transition structure between ESIW and a WR-3 rectangular waveguide.

Photonic Neuromorphic Processing With Coupled Spiking Silicon Microrings

open access: yesLaser &Photonics Reviews, EarlyView.
A neuromorphic photonic core composed of three self‐pulsing silicon microring resonators is experimentally demonstrated for analogue and digital processing. Richer computational capabilities emerge under injection conditions where the dynamics are nonlinear and coupled, yet remain reproducible, opening novel strategies for future on‐chip training and ...
