Summary: In this study, a compact electro-optic modulator is integrated on the endfaces of a single-mode optical fiber jumper for fast amplitude modulations. It utilizes ultrathin and high quality-factor plasmonic metasurfaces, nanofabrication-friendly and highly efficient EO polymers, and coupling-free connections with fiber networks. The modulator allows dual-band operations and high-speed modulations.

Summary: Silicon photonics, as an important optoelectronic integration platform, has advantages of low power consumption, low cost, and CMOS compatibility. However, conventional silicon modulators have limitations, leading to the need for new structures to improve their performance. Slow-light effect, which reduces the group velocity of light, is an attractive research point for reducing the device footprint. This paper reviews the recent progress of silicon-based slow-light electro-optic modulators and discusses the challenges and development directions for practical applications.

Summary: Research in optical metasurfaces has grown rapidly in recent years due to their ability to completely control transmitted and reflected fields. This study demonstrates electrically tunable optical metasurfaces that operate as optical free-space modulators in reflection. Intensity modulation is achieved using the electro-optic Pockels effect and tuning the Fabry-Perot resonance.

Summary: The study focuses on the polaritonic bandstructure of a 2D atomic lattice coupled to a surface plasmon polariton mode in the single excitation regime. By using a computational technique based on Dirichlet-to-Neumann map, a 2D atomic lattice is designed using only two-level atoms with an isolated flat polaritonic band where the group velocity for the modes approach zero across the Brillouin zone. Such a system could be utilized for slowing, storing, and manipulating single photons in a 2D geometry.

Summary: This research demonstrates a highly linear lithium niobate (LN) modulator with an ultra-high spurious-free dynamic range (SFDR) using a ring-assisted Mach-Zehnder interferometer configuration. The modulation does not require active feedback controls to suppress third-order intermodulation distortions (IMD3), resulting in a significant improvement over previous results in the thin-film LN platform.

Summary: This work presents two slow-light enhanced silicon optical modulators with electro-optic phase shifter lengths of 500 μm and 150 μm, fabricated using the AIM Photonics foundry. Tunable power splitters result in a threefold increase in the extinction ratio. Operating at 10 Gbps, an eye diagram was achieved with a very low signal voltage of V-pp = 500mV. The energy per bit is 57.5 fJ/bit and 45 fJ/bit for the 500 μm and 150 μm modulators, respectively. The devices' nonlinearity was measured, yielding a spur-free dynamic range of 113.2 dB/Hz(2)/(3). The 150 μm length MZM is one of the smallest optical modulators using Bragg gratings for slow light ever reported, with an estimated modulation efficiency of 0.33 V·cm.

Summary: Subwavelength electromagnetic field localization has been the focus of photonic research in the last decade, showing potential for enhancing sensing capabilities and increasing coupling between photons and material excitations. Research has revealed a limit to the possibility of arbitrarily increasing electromagnetic confinement in polaritonic systems. Strongly subwavelength fields can excite high-momentum propagative magnetoplasmons, leading to nonlocal polaritonic effects.
