Chirped cladding is proposed as a novel tailoring tool to simultaneously attain wider transmission window and reduced temporal dispersion in an all-solid Bragg-like microstructured optical fiber as compared to its perfectly periodic cladding counterpart. This design route for photonic bandgap microstructured fibers could be exploited as an additional degree of freedom for bandgap engineering. A...

In this chapter, we will review the progress of using tellurite glass nonlinear fibers for mid-infrared nonlinear applications in this chapter. First, we introduce various fabrication approaches for making conventional solid core/clad tellurite glass preforms and structured tellurite glass preforms. Second, two technical difficulties have been found during the early stage of using small-core te...

The Faraday effect provides a mechanism for achieving unidirectional light propagation in optical isolators; however, miniaturization requires large Verdet constants. High rare-earth content glasses produce suitably large Verdet values, but intrinsic fabrication problems remain. The novel powder-intube method, or a single-draw rod-in-tube method, obviates these difficulties. The powder-in-tube ...

This experiment exposed a sample of U.S. undergraduates (43 men, 40 women) to suggestively or conservatively clad virtual females who exhibited either responsive, high eye gaze or nonresponsive, low gaze in an immersive virtual environment. Outside the virtual world, men and women who encountered a highly stereotypical character—a suggestively clad, high gaze agent (“vamp”) or conservatively cl...

We report a novel spontaneous soliton pattern formation in a figure-of-eight passively mode-locked erbium-doped double-clad fiber laser. It consists in a condensate phase in which there is almost periodic arrangement of alternate crystal and liquid soliton phases. Thanks to an adapted ansatz for the electric field, we perform a reconstruction allowing to clearly identify the soliton distributio...
