Article Abstract
Counter-propagating optical tweezers are experimental platforms for the frontier exploration of science and precision measurement. The polarization of the trapping beams significantly affects the trapping status. Using the T-matrix method, we numerically analyzed the optical force distribution and the resonant frequency of counter-propagating optical tweezers in different polarizations. We also verified the theoretical result by comparing it with the experimentally observed resonant frequency. Our analysis shows that polarization has little influence on the radial axis motion, while the axial axis force distribution and the resonant frequency are sensitive to polarization change. Our work can be used in designing harmonic oscillators which can change their stiffness conveniently, and monitoring polarization in counter-propagating optical tweezers.

Optical cooling is a key technique for preparing ultracold atoms in quantum technologies and precision experiments. We employ shortcut-to-adiabaticity (STA) techniques to accelerate and stabilize laser-based atomic cooling protocols. This approach improves the performance of conventional adiabatic momentum transfer schemes by addressing key limitations such as Doppler shifts, laser intensity fluctuations, and spontaneous emission.

Quantum key distribution (QKD) is a secure communication method for sharing symmetric cryptographic keys based on the principles of quantum physics. Its integration into the fiber-optic network infrastructure is important for ensuring privacy in optical communications. Multi-core fibers (MCFs), the likely building blocks of future high-capacity optical networks, offer new opportunities for such integration.

The two-mode dynamics of the counter-propagating modes - clockwise (CW) and counterclockwise (CCW) and their selection have gained attention in the mid-infrared; however, the underlying switching mechanism has been largely unexplored. Previously, we experimentally demonstrated robust and deterministic mode selection in a ring quantum cascade laser (QCL) with an active outcoupling waveguide.

We generate a series of long, time-shifted, self-synchronizing maximum-length pseudo-noise (PN) codes in the form of an array of intensity-modulated beams from a single aperture, using only two traveling-wave acousto-optic deflectors (AODs). The cascaded AODs, driven by counter-propagating acoustic waves, are imaged onto each other, and the diffracted fields are imaged onto the far field target, where the interferometric product between two binary phase-shift keying (BPSK)-encoded maximum-length (ML) sequences generates time-permuted versions of the PN code as an array of beams highly identifiable as well-separated peaks in the cross-correlation.

The MFOSI setup employs sinusoidal phase modulation and lock-in detection to measure the non-reciprocal phase shift between counter-propagating waves.
