Design of a new narrow band channel drop filter based on photonic crystal ring resonator

In this design an optical ring resonator are embedded between two Horizontal input and output waveguides which has 4 orbitals around the center of the resonator so that each orbital consists of 8 rods with different size in which radius of larger orbitals rods are bigger than radius of smaller orbitals rods. The analysis of simulation results showed the proposed filter has the transmission effi...

Low Level Narrow Band Red Light Treatment of Acne Vulgaris

Phototherapy treatment using low intensity visible red light (laser) for wound healing is well known. However, its worldwide use is prohibitively expensive and requires a clinical setting. Using a handy, safe and inexpensive non-coherent low level narrow band red light device (LLRL), we performed a prospective clinical trial on 53 patients suffering from Acne Vulgaris. The patients were divided...

ACS CCDs UV and narrow- band filters red leak check

We present results of the observations of the star 15 Mon, obtained with the aim of checking the impact of red leaks in the UV (and U-band) and two narrow-band filters on ACS CCDs. The red leak in the F220W, F250W and F330W filters appears to be smaller than measured in pre-flight tests. We derive updated passbands for the three filters and we present the updated correction table for different ...

An Integrated High-Frequency Narrow-Band High-Resolution Synthesizer

A frequency synthesizer employing a new digitalfrequency measurement method in a feedback loop is described. The synthesizer features high-frequency resolution and a high operating frequency. The mostly digital nature of the synthesizer and relaxed voltage-controlled oscillator requirements also make the synthesizer suitable for integration. Models for the synthesizer are developed and experime...

Evaluation of Efficacy and Safety of Combination of Narrow Band Ultraviolet B and Topical Calcipotriol Versus Narrow Band UVB alone in the Treatment of Vitiligo

Background: Narrow band Ultraviolet B (NBUVB) has been used successfully for the treatment of vitiligo. Recently, topical calcipotriol has also been used as immunotherapy or as a part of combination therapies. The aim of this study was to compare the clinical efficacy and safety of NBUVB and NBUVB plus topical calcipotriol in the treatment of generalized vitiligo.Methods: NBUVB phototherapy was...
