Toward Highest Frequency, Phase‐Sensitive Electric Field Sensing Enabled by Plasmonic Circuits

Laser &Photonics Reviews, EarlyView.
An electromagnetic field sensor using an optical sensor head for distortion‐free, high‐sensitivity measurements with potential for high‐frequency operation is presented. The frequency response is enabled by an antenna‐integrated plasmonic modulator. The sensitivity is calculated, and optimizations to obtain thermal‐background‐limited sensitivity are ...

Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes

Laser &Photonics Reviews, EarlyView.
This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip

Integrated Photonic Modulator Circuit With Programmable Intensity and Phase Modulation Response

Laser &Photonics Reviews, EarlyView.
A platform‐agnostic programmable modulation circuit is introduced to enable tunable and universal optimization of integrated photonic modulators. By flexibly controlling carrier amplitude and phase, the approach adapts to diverse device characteristics without structural redesign.

Quantization of Polaritons Confined in Dielectric Structures

Laser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands

Laser &Photonics Reviews, EarlyView.
E/O modulators typically face a trade‐off between bandwidth and modulation efficiency. An integrated E/O modulator is presented that simultaneously achieves wideband, large bandwidth, and high modulation efficiency operation by embedding a partially overlapped double‐layer graphene on a compact silicon slot‐waveguide microring resonator.
