Purpose Kretschmann-configuration has been used as a subwavelength framework to detect tiny ‎alterations of the refractive index of biomaterials. However, most of the theoretical assessment of such configuration ‎is usually based on the plane wave excitation transfer matrix method (TMM) of prism-‎coupled to thin metal film supporting plasmonic modes. Accordingly, a better theoretical framework ‎than the plane wave approximation is indispensable for reliable and accurate assessments and ‎simulations. A reformulated form of the traditional FFT-BPM has been adapted to evaluate the performance and characteristics of surface plasmonic waveguide biosensor. Method Surface plasmon mode is excited by a sub-wavelength narrow light beam. The highly confined optical energy of that plasmonic mode enables an ‎efficient means to detect tiny variations in the composition of ‎the analyte in contact with the metallic layer of the surface plasmon ‎guide. The plasmonic guided power is detected thereafter electronically via an optical MOS capacitor. Results the guided plasmonic power has been used to assess the fundamental characteristics and performance of the sensor, namely the linearity, sensitivity, and figure of merit as well as the full width at half maximum (FWHM). Conclusion The proposed sensor could be integrated to a wide class of angular measurement system (for instance goniometer) or via electronic detection of the optical plasmonic guided power. we claim that this work is worthy of being shared with researchers and ‎developers interested in the experimentation and assessment of sensitive biosensors; especially in ‎case when complicated and sophisticated analysis tools represent an unpleasant burden.

Graphene as a truly 2-dimensional (2D) system is a promising candidate material for various optoelectronic applications. Implementing graphene as the main building material in ultra-broadband photodetectors has been the center of extensive research due to its unique absorption spectrum which covers most of the electro-magnetic spectra. However, one of the main challenges facing the wide application of pure graphene photodetectors has been the small optical absorption of monolayer graphene. Although novel designs were proposed to overcome this drawback, they often need complicated fabrication processes in order to integrate with the graphene photodetector. In this regard, fabrication of purely graphene photodetectors is a promising approach towards the manufacturing of simple, inexpensive, and high photosensitive devices. The fabrication of full graphene photodetectors (FGPDs) is mainly based on obtaining an optimal technique for the growth of high quality graphene, modification of electronic and optical properties of the graphene, appropriate techniques for transfer of graphene from the grown substrate to the desire position, and a proper design for photodetection. Therefore, the available states of the art techniques for each step of device fabrication, along with their pros and cons, are reviewed and the possible approaches for optimization of FGPDs have been proposed.
