Karthika Muthukrishnan,Manoj Vanaraja,Shanmugam Boomadevi,Rakesh Kumar Karn,Vijay Singh,Pramod K. Singh,Pramod K. Singh,Krishnamoorthy Pandiyan +7 more
TL;DR: In this article, the authors have discussed the gas sensing characteristics of Zinc Oxide thin films prepared by dip coating method using Zinc nitrate hexahydrate (Zn (NO3)2)2 and organic polymer Na-CMC as a starting material.
Journal ArticleDOI
Nondestructive quality evaluation of periodically poled lithium niobate crystals by diffraction.
TL;DR: An expression for the noise between the diffraction orders from a random grating was derived and applied to analyze the statistical duty-cycle error in PPLN, providing an efficient means for poling quality evaluation.
Journal ArticleDOI
Tunable all-optical wavelength broadcasting in a PPLN with multiple QPM peaks
TL;DR: Tunable multiple-idler wavelength broadcasting of a signal to selective channels for wavelength division multiplexing (WDM) based on cascaded χ(2) nonlinear mixing process in a novel multiple-QPM 10-mm-long periodically poled LiNbO3 having an aperiodic domain in the center is demonstrated.
Journal ArticleDOI
Collinear broadband optical parametric generation in periodically poled lithium niobate crystals by group velocity matching
TL;DR: In this paper, the authors designed and experimentally demonstrated a collinear broadband optical parametric generation (OPG) using periodically poled lithium niobate (PPLN) crystals with quasi-phase matching (QPM) periods of 215, 240, and 270 µm.
Journal ArticleDOI
Ultra-broadband optical parametric generation and simultaneous RGB generation in periodically poled lithium niobate.
TL;DR: The ultra-broadband OPG led to efficient collinear RGB generation from a single PPLN crystal at a fixed pump wavelength and the green and red beams were found to be originating from high-order QPM sum-frequency generation between the pump and selected frequencies in the OPG band.
