“…It is worth noting that the response time scale of the nonlinear effect of EO polymer is in the femtoseconds range so that it can be ignored . Thus, the frequency limitation is typically determined by two factors, cavity lifetime and the RC constant. , For the cavity lifetime, it is determined by the calculated Q factor (about 203), which equates to a bandwidth of 1.14 THz. Therefore, the electro-optic bandwidth of the device is mainly constrained by the RC time constant ( f 3 dB = 1/2πRC).…”

Spatial light modulators (SLMs) that could control diverse optical properties are highly demanded by many optoelectronic systems. Recently, the integration of nonlinear χ (2) materials and metasurfaces has been recognized as a promising strategy for next-generation SLMs. However, their modulation efficiency still encounters challenges due to low quality factor and weak light−matter interaction. Here, we demonstrate an efficient SLM by manipulating the dual bound state in continuum (BIC) with the assistance of a binary-pore anodic alumina oxide template technique. The coexistence of symmetry-protected BIC and Fabry− Peŕot BIC is obtained by a desirable sandwich configuration with a BIC metasurface and EO polymer, which efficiently restrain radiative loss and generate a strong quasi-BIC resonance. The assembled SLM with large absorption and Q-factor delivers a modulation depth of 77% and an f 3 dB of nearly 100 MHz. This dual BIC metasurface provides potential for applications including switches, LIDAR, augmented and virtual reality, and so on.

“…Furthermore, for the lumped EOM device, we also evaluate the theoretical 3-dB bandwidth f 3dB of the metafiber EOM. f 3dB can be calculated using the equation: (1/f 3dB ) 2 = (2πτ) 2 + (2πRC) 2 , where τ is the photon lifetime, R and C are the resistance and capacitance of the device system, respectively 55 . The plasmonic-organic hybrid structure can be regarded as a parallel-plate capacitor, as depicted in the left of Fig.…”

Digitalizing optical signals through electric driving signals, electro-optic modulators (EOMs) are one of the cardinal elements in modern optical communications. Most of current EOM devices are targeting on-chip integrations, which routinely suffer from high coupling losses, complex optical alignments and single-band operations. In this study, we for the first time integrate a lumped EOM device on the endfaces of a single-mode optical fiber jumper for fast amplitude modulations. Profiting from ultrathin and high quality-factor plasmonic metasurfaces, nanofabrication-friendly and highly efficient EO polymers and coupling-free connections with fiber networks, our EOM is demonstrated to allow dual-band operations (telecom O band and S band) and high-speed modulations (~1 GHz at a bias voltage of ±9 V). This work offers an avenue to ‘plug-and-play’ implementations of EO devices and ultracompact “all-in-fibers” optical systems for communications, imaging, sensing and many others.

“…Moreover, their wavelength selectivity enables dense wavelength division multiplexed links at the micrometer scale and consequently increases aggregate link bandwidth drastically. [8][9][10] Up until now, ring modulators have been realized by using a number of material platforms, such as silicon (Si), EO polymer, and crystals. [11][12][13] Recent progress of Si modulators relying on the free-carrier plasma-effect is of interest and offers a realistic means of achieving ultra-fast data transfer, enabled by a careful balance among the doping configuration, loss control, and free-carriers' lifetime.…”

Advanced photonic integrated circuits require large-scale integration of high-speed electro-optic (EO) functional components on a chip. Low power consumption and high operation speed are thus key metrics for almost all integrated EO devices. Here, we demonstrated a ring resonator modulator based on lead zirconate titanate (PZT) on a SiO2/Si substrate. The ridge waveguides were employed to keep a large spatial overlap between the optical field and the electric field within the PZT layer. The device exhibits a data rate of 56 Gbit/s and significant tuning efficiency, reaching up to 35.8 pm/V, corresponding to 1.17 V·cm. The demonstration of energy efficient and high-speed EO modulation paves the way for realizing dense PZT photonics integrated circuits.
