High‐Energy Femtosecond All‐Fiber Laser Systems in 1.7–1.8 μm Using a Normal‐Dispersion Tm‐Doped Fiber

Advanced Photonics Research, EarlyView.
High‐energy ultrafast all‐fiber lasers are demonstrated in the 1.7–1.8 μm range using a novel Tm‐doped fiber with depressed cladding for dispersion tailoring and short‐pass filtering. A parabolic core enhances optical gain, overcoming poor gain overlap in conventional depressed cladding fibers.

Modal Theory of Phase‐Modulated and Frequency‐Shifting Ring Cavities

Advanced Photonics Research, EarlyView.
We present a theoretical and experimental characterization of the optical modes of dispersionless ring cavities with phase modulators or frequency shifters. Their response to arbitrary modulation acts as a filter for phase‐modulated modes that determine the optical output of passive resonators and lasers. This provides a general framework for analyzing

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides

Advanced Photonics Research, EarlyView.
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...

Experimental Test of the Three‐Setting Clauser–Horne–Shimony–Holt Inequality with Nonmaximally Orbital Angular Momentum Entangled States

Advanced Photonics Research, EarlyView.
Herein, the maximum violation of the three‐setting Clauser–Horne–Shimony–Holt (CHSH) inequality using nonmaximally entangled photons with orbital angular momentum is demonstrated. By mapping the optimization problem to maximizing a triangle's perimeter inscribed in an ellipse, the experiment validates the geometric approach and highlights the ...
