Crystalline SiC has been doped with a p-type dopant using a laser doping technique to create an intermediate energy level within the bandgap of SiC. The energy gap between this acceptor level and the valence band of SiC is designed to match the midwave infrared (MWIR) wavelength (3–5 μm) of the photons that need to be detected. Although this study presents results pertaining to MWIR detection, the approach to creating intermediate energy levels can be utilized to fabricate crystalline semiconductor-based broadband detectors and emitters in the MWIR range.

Traditional evanescent wave optical biosensors generate an electromagnetic wave at the sensor surface that penetrates 100–200 nm into the analyzed aqueous medium [1]. This has proven to be a highly sensitive tool to monitor refractive index changes in the close vicinity of the sensor probe and well suited to monitor thin films of biomolecules (proteins, DNA etc.). However, in several recent applications a larger penetration depth is needed or the probing volume must be precisely controlled to monitor refractive index variation in living cells cultured on the sensor surface. Embedding low refractive index materials (such as nanoporous silica with refractive index 1.2) or nanometer scale metal films (with negative real part of their complex dielectric constants) in the sensor structures the penetration depth can be significantly extended and fine tuned (Fig. 2a) [1–6]. Using several modes even the optical sectioning of the cell sample is feasible (Fig. 2bc) [6].

We examine performance versus complexity tradeoff for nonlinear compensation using frequency-shaped backpropagation. High residual dispersion per span gives better asymptotic performance at high complexity, but this is not necessarily true at intermediate complexities.
