An asymmetric Mach-Zehnder electro-optic modulator is fabricated through etching in 500nm thin film of Y-cut Lithium Niobate. A half wave voltage length product of 16.8Vcm and modulation efficiency of 9.4×10−3V−1 were measured for this device which is very close to what we expect from theory.

Silicon PMTs revolutionized the High Energy Physics instrumentation, first for the Calorimeters. Exploiting the Silicon PM technology and beyond, their pixel structure and avalanche regime, leads to novel tracking techniques, either applied to large area tracking systems or digital 3D avalanche pixel devices.

We demonstrate a frequency-stabilized, dual-Kerr microcomb that guides an integrated Vernier-laser optical frequency synthesizer, all derived from an RF clock. The synthesizer's stability is <10−12/τ with Hz-level tuning resolution across a 32 nm tuning range.

A flexible wireless Data Center (DC) network based on precise steerable Free Space Optical (FSO) links is described as a promising solution to meet future DC demands of high-throughput, with robustness to dynamic traffic patterns, reducing cabling complexity and increased energy efficiency. Robust and precise steerable FSO links over dynamic traffic play a key role in the reconfigurable optical wireless DC inter-rack networks. In this work, we propose and demonstrate a reconfigurable 10 Gbps FSO system incorporating a smart beam acquisition and tracking mechanism based on gimbal-less two-axis MEMS micro-mirror and retro-reflective film marked aperture. The fast MEMS-based beam acquisition switches laser beam of FSO terminal from one rack to the next for reconfigurable networking, and the precise beam tracking makes FSO device auto-correct any misalignments in real-time. We present the measured optical power loss and b it e rror rate performance of steerable FSO links in various directions. Experimental results suggest that the MEMS based beam steerable FSO links hold merit for future reconfigurable wireless DC networks.

We experimentally demonstrate pulsed Airy beams that are diffraction-free and acceleration-free by introducing a tight correlation between the spatial and temporal spectra of a femtosecond-pulsed beam via a two-dimensional pulse shaper. Such beams only exhibit transverse acceleration only in the pulse local time-frame.

Expansion microscopy (ExM) is a new tissue preparation technique that has the potential to revolutionize immunofluorescence imaging for histology [1, 2]. By physically expanding a biological specimen embedded in a dense swellable polymer, one can achieve an effective increase in resolution of «5X using an ordinary fluorescence microscope. The probes used for immunofluorescence in ExM are standard fluorescent conjugated antibodies and proteins. The photosensitivity of these fluorophores limit their usable lifetime and emission brightness. These limitations significantly reduce their effectiveness in ExM since the 5X lateral expansion results in an ≈125X reduction in signal per focal volume. In addition, traditional fluorophores have broad excitation and emission spectra that limit multiplex imaging to the number of spectra that can “fit” into the spectral bandwidth, largely comprising visible wavelengths.

This work reports generation of a 128-GHz optical pulse train starting from a 250-MHz CEO-stabilized frequency comb, by means of dispersion-induced repetition-rate multiplication by temporal self-imaging. This demonstration should prove useful in bridging the current gap between CEO-stabilized MHz-rate pulse trains and highly demanded GHz-rate ones.

We investigate basic nonlinear effects in optical fibers which opto-geometrical parameters oscillate along the propagation axis. These “topographic” fibers provide an additional degree of freedom leading to multiple quasi-phase matched modulation instability side lobes in single pass configuration or in passive cavities. Experimental results are confirmed by analytical and numerical ones.
