Design and Study of Low Loss, High Birefringence Quasi-Symmetric Hollow-Core Anti-Resonant Fiber
PhotonicsLow-loss, high-birefringence, bend-resistant hollow-core anti-resonant fibers for infrared wavelengths have important applications in the fields of precision interferometric sensing, laser systems, and optical communications. In this paper, an eight-tube

Low loss etchless silicon photonic waveguides
Optics Express, 2009 We demonstrate low loss silicon waveguides fabricated without any silicon etching. We define the waveguides by selective oxidation which produces ultra-smooth sidewalls with width variations of 0.3 nm. The waveguides have a propagation loss of 0.3 dB/cm at 1.55 microm. The waveguide geometry enables low bending loss of approximately 0.007 dB/bend for a

O-star mass-loss rates at low metallicity
, 2012 Mass fluxes J are computed for the extragalactic O stars investigated by Tramper et al. (2011; TSKK). For one early-type O star, computed and observed rates agree within errors. However, for two late-type O stars, theoretical mass-loss rates underpredict

Strategy for Low‐Loss Optical Devices When Using High‐Loss Materials
Advanced Photonics Research, 2022 Material loss, especially in metal and 2D materials, is the bottleneck for high‐performance integrated optical devices. Here, a novel concept by utilizing the high‐loss materials in a non‐Hermitian system instead of avoiding the loss materials.

Quantitative Low Loss and Ultra Low Loss Spectroscopy in the STEM
Microscopy and Microanalysis, 2001 Abstract Many of the topics in valence spectroscopy originally pioneered with TEM equipment have now been taken over by STEM. Notable exceptions are the studies by J. Silcox and his colleagues of plasmon dispersion and of the guided modes in thin slabs where retardation and other relativistic effects arise.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.

Low-loss, circularly-polarized dichroic plate [PDF]
, 1975 Dichroic plate has orthogonally-disposed, loaded dipole apertures with their orientations arranged so as to cancel cross-coupling effects which would otherwise result in power loss to circularly polarized ...

Mass loss and very low-metallicity stars [PDF]
, 2007 Mass loss plays a dominant role in the evolution of massive stars at solar metallicity. After discussing different mass loss mechanisms and their metallicity dependence, we present the possibility of strong mass loss at very low metallicity.
