“…In Equation (A4), ω h , ω l are limiting frequencies of the source power spectrum. For the sake of simplicity, we assume that the source power spectrum is a normal distribution function (with standard deviation equals to 0.02 THz and 0.01 THz [44,45]) and an ideal detector (r = 1). With S 11 from the simulation, P o can be calculated using Equation (A4), then the device performance with finite band excitation can be acquired:…”

We propose a spectrometer-free refractive index sensor based on a graphene plasmonic structure. The spectrometer-free feature of the device is realized thanks to the dynamic tunability of graphene’s chemical potential, through electrostatic biasing. The proposed sensor exhibits a 1566 nm/RIU sensitivity, a 250.6 RIU−1 figure of merit in the optical mode of operation and a 713.2 meV/RIU sensitivity, a 246.8 RIU−1 figure of merit in the electrical mode of operation. This performance outlines the optimized operation of this spectrometer-free sensor that simplifies its design and can bring terahertz sensing one step closer to its practical realization, with promising applications in biosensing and/or gas sensing.

“…Among them, the VBG is the preferred device for high power narrowlinewidth OPOs because of the strong wavelength stability. In 2015, by using the VBG as a reflective mirror, Peng et al reported a high-power, narrow-bandwidth mid-infrared MgO:PPLN OPO at 2907.55 nm with an idler bandwidth of 0.68 nm and an average output power of 51.7 W, corresponding to a signal wavelength of 1679.11 nm with a bandwidth of 0.12 nm [12]. However, the reflectivity peak of the VBG can only be tuned slightly via temperature tuning with a slope of 0.014 nm/K.…”

A high-power narrow-linewidth 1.55 μm pulsed laser, based on MgO:PPLN OPO, has been achieved using a F–P etalon. The pump source is a 1064 nm acousto-optical (AO) Q-switched Nd:YAG laser with a repetition rate of 10 kHz. Under the maximum pump power of 18 W, the signal output power of 2.57 W is demonstrated at 1551.1 nm with a linewidth of 0.07 nm, corresponding to a slope efficiency of 16.1%. Different from traditional inversion lasers, the narrow-linewidth wavelength tunability of approximately 1.55 μm can be realized by changing the temperature.

“…The three most popular tuning techniques for PPLT OPOs are angle, temperature, and periodic tuning. The commonly used PPLT crystals include singleperiod, multi-period, mix-period, and fan-out crystals [10][11][12]. Single-period crystals have only one fixed period.…”

We reported a high-efficiency, broad-linewidth, wide-tuning-range singly-resonated optical parametric oscillator (OPO) based on a fan-out PPLT crystal. When the PPLT crystal was operated at 120 °C and pumped by Q-switched 1064 nm laser at 14.17 W with a circular pump profile, the overall output power of OPO was 7.22 W (η = 50.4%) for both the signal and idler waves. The central wavelength and linewidth of the mid-infrared (MIR) laser were 3770 nm and ∼40 nm. A wavelength tuning range of 3538–3941 nm was accomplished by adjusting the crystal period through simple mechanical movement. Due to the larger coverage of gratings with an elliptical pump profile, the output linewidth of the MIR laser was further broadened to ∼100 nm, which is ten times more than other non-fan-out PPLT OPOs. Both pumping methods with different profiles were operated at 30 kHz, 49.2 ns for the 1064 nm laser, the power fluctuation of the obtained MIR laser was within 3.5%.
