It is defined as min\(\left(\left| \frac{R{_{{\mathrm{NB}}}-R_{{\mathrm{B}}}{R_{{\mathrm{B}}}\right| , \left| \frac{R_{{\mathrm{NB}}}-R_{{\mathrm{B}}}{R_{{\mathrm{NB}}}\right| \right)\) and it is plotted in the range 800–1100 cm−1 for both 3 ...
and OPAs) are among the favorite methods10,20,21, providing widely tunable, relatively broadband coverage (1000 cm − 1) in both the shortwave infrared (SWIR), that is, the spectral range from 2000 to 5000 cm − 1, and the longwave infrared (LWIR), from 500 to 2000 cm − 1. ...
Here, we have described mode localization in the PBG, energy and decay length associated with it. We have limited our study only in the mid-IR region by considering frequency range varying from 20THz(~667cm−1) to 55THz(~1835cm−1). The chosen parameter for layer thickness in our ...
In the mid-infrared (MIR) spectral range, a series of applications have successfully been shown in the fields of sensing, security and defense, energy conservation, and communications. In particular, rapid and recent developments in MIR light sources have significantly increased the interest in devel...
This Review discusses the emerging field of mid-infrared frequency comb generation, including technologies based on novel laser gain media, nonlinear frequency conversion and microresonators, as well as the applications of these combs in precision spectr
This source generated mid-IR at 3 microns with a powers of ~2.5 microW and a spectral linewidth of less than 30 MHz. A frequency tuning range of 300 GHz (10 cm-1) was obtained by varying the current and temperature of the DFB laser diode. A high-resolution NH3 absorption Doppler-...
Active mid-infrared (MIR) imagers capable of retrieving three-dimensional (3D) structure and reflectivity information are highly attractive in a wide range of biomedical and industrial applications. However, infrared 3D imaging at low-light levels is still challenging due to the deficiency of sensitive...
Sample pitch was 0.1 mm. This measurement reveals a significant enhancement in uniformity (smaller range of loss values) for the hybrid mirrors, likely given the reduced defect density from the single bonding step. Photos of example mirrors are shown in the insets. Full size image...
