To analyse the performance of tapered and MMI assisted splitter on the basis of geographical parameters

The design and performance analysis of a 1310/1550-nm wavelength division demultiplexer with tapered geometry based on InP/InGaAsP multimode interference (MMI) coupler has been carried out. Wavelength response of demultiplexer of conventional MMI and tapered input and tapered output (tapered I/O) waveguides geometry of the MMI have been discussed. The demultiplexing function has been first performed by choosing a suitable refractive index of the guiding region and geometrical parameters such as the width and length of MMI structure have been achieved. Access width of tapered I/O waveguides have been adjusted to give a low insertion loss (IL) and high extinction ratio (ER) for the considered wavelengths of 1310 nm and 1550 nm. The total size of the demultiplexer has been significantly reduced over the existing MMI devices. Numerical simulations with finite difference beam propagation method are applied to design and optimize the operation of the proposed demultiplexer.

The use of nanotechnology products in biomedicine has led to the emergence of a hybrid science known as nano-biotechnology. Due to the nanoscale nature of most biological systems, nanoscale materials integrate well into biomedical devices. In response to certain stimuli, highly ordered bottom-up nano-structured materials exhibit specific behaviours. Nanomaterial applications are tuned by surface chemistry and physics. This chapter provides an overview of the use of metallic, metal oxide, and carbon nanoparticles for specific biomedical applications. It also discusses liposomes and nano-patterned flat surfaces. A challenge is determining the effects of nanomaterials on biological systems. However, a detailed understanding of nanomaterial potential toxicity is needed to take advantage of their potential applications in medicine. To minimize false results, it is important to interpret the relationship between toxicity and physicochemical properties cautiously.
