The CH317OH isotopic form of methanol has been investigated as a far-infrared laser medium for the first time. Using two distinct experimental systems, this investigation has resulted in the discovery of twelve far-infrared laser emissions that range in wavelength from 69.7 to 642.9 μm. Along with the wavelength, each laser emission is reported with its optimal operati... View full abstract»

The role of gain in an optical filter is advanced by good agreement between theory and experiment presented herein. The particular integrated photonic filter is composed of four semiconductor optical amplifiers and one four-port coupler located at the intersection of the amplifiers. The four-port coupler is realized using frustrated total internal reflection off a very thin slab of alumina embedde... View full abstract»

We report a novel approach for increasing the output power in passively mode locked semiconductor lasers. Our approach uses epitaxial structures with an optical trap in the bottom cladding that enlarges the vertical mode size to scale the pulse saturation energy. With this approach we demonstrate a very high peak power of 9.8 W per facet, at a repetition rate of 6.8 GHz and with pulse duration of ... View full abstract»

A continuous-wave diamond Raman laser is demonstrated with an output power of 5.1 W at 1217 nm. This Raman laser is intracavity pumped by a side-pumped Nd:YLF rod laser: a 43-fold brightness enhancement between the Nd:YLF and diamond Raman lasers is observed, with the M2 beam propagation factor of the diamond Raman laser measured to be <; 1.2. Although higher output powers are demons... View full abstract»

In this paper it is shown that, once a particular erbium-doped-silica photonic crystal fiber has been fabricated, the characteristic parameters obtained by means of the technique developed by the authors can be used to properly simulate the main features of optical amplifiers and lasers made of this fiber. This requires assuming that the finite size of the air-holes microstructure makes the overal... View full abstract»

We report a method to improve the beam quality of broad area lasers by using a V-shaped external cavity formed by two off-axis feedback mirrors that allow to select a single transverse mode with transversally modulated intensity distribution. In the case when one of the two feedback mirrors is absent a spontaneous formation of self-induced transverse population grating leading to a reduction of th... View full abstract»

A design of near- to mid-infrared tunable multichannel filter (MCF) based on the doped semiconductor-dielectric photonic crystal (PC) heterostructure is proposed. Here, a strongly extrinsic semiconductor, n-type germanium (n-Ge), is used as one of the constituent layers. The occurrence of multichannel feature originates from the negative-permittivity in the highly doped n-Ge. ... View full abstract»

The photovoltaic properties of (0001) face GaN/InGaN p-i-n solar cell are studied numerically. The simulation results show that the detrimental effects of hetero-interfaces and polarization charges will seriously degrade the solar cell performance, especially when the indium composition is high. If these effects are not eliminated or diminished, the photovoltaic properties would not be good enough... View full abstract»

We present experimental results on the performance of a series of coated, D-shaped optical fiber sensors that display high spectral sensitivities to external refractive index. Sensitivity to the chosen index regime and coupling of the fiber core mode to the surface plasmon resonance (SPR) is enhanced by using specific materials as part of a multi-layered coating.

We analyze two linearly polarized modes in an elliptical micropillar cavity through Fourier space analysis, where the in-plane wavevector corresponds to the incidence angle with the distributed Bragg reflector (DBR). The Fourier space field pattern shows that the spreading angle along the short axis is larger, so that it has the greatest effect on the reflectivity. The higher quality factor (Q<...
