Applications Of Photonic Circuits

The base of the light triangle, b, was measured first. Then, the light positions, a, were measured f=or the first order (m=1) and second order (m=2) light beams to determine the angle Ɵ for each. This data was organized in an Excel table and used to find the wavelength, λ, of the laser through Equation 1. This value was then compared to the theoretical value for wavelength of the laser, which was 6.328x〖10〗^(-7)m, and the percent error was calculated between the two.

Since their discovery in the early 1990s, there has been intense activity exploring the electrical properties of these systems and their potential applications in electronics.

Anjali Khatri et al 2013 proposed a micro molded U-shaped PDMS optical waveguide for biosensing applications using soft lithography technique. Due to its low refractive index contrast compared to SU-8 in the sensing region, it finds lot of application in biosensing. They reported that PDMS based waveguides were exhibits five-fold more sensitive than SU-8. Ease of fabrication, high sensitivity and mechanical robustness of PDMS finds a promising and versatile platform for biosensor

Lasers are recognized from other light sources by their intelligibility. Spatial soundness is regularly communicated through the yield being a slender pillar, which is diffraction-restricted. Laser pillars can be engaged to extremely small spots, accomplishing a high irradiance, or they can have low difference to aggregate their energy at an awesome separation.

As discussed, the use of single-dot architecture could be combined in unique ways with linear optical schemes. [SOURCE] Economou et al. support this idea, stating “[s]pins…have received a great deal of attention because they interact strongly with light and provide the opportunity for ultrafast all-optical implementation of logical operations.” While the negative implications of that statement, especially in decoherence caused by environmental interaction, have been discussed, there are many potential benefits as well. Foremost among these is the

.Where, ΔI and Δn are the intensity variation and the surrounding effective refractive index. Sensitivity can be divided into two types, device sensitivity, and waveguide sensitivity.

Gallium nitride (GaN) is a binary III/V direct bandgap semiconductor with a bandgap of 3.4 eV commonly used in light-emitting diodes since the 1990s. GaN has a low sensitivity to ionizing radiation which makes it a suitable material for solar panels on satellites. Various military and space application also benefit from the usage if this radiation hardened material. Besides the wide bandgap, high breakdown field and high saturation velocity of GaN make it very promising for high power, high-speed and high temperature electronic devices. GaN devices offer five key characteristics: high dielectric strength, high operating temperature, high current density, high speed switching and low on-resistance. These characteristics are due to the properties of GaN, which, compared to silicon, offers ten times higher electrical breakdown characteristics, three times the bandgap, and exceptional carrier mobility. Low resistance Ohmic contacts with a smooth morphology, and good edge acuity and thermal stability are imperative in the successful implementation of all these devices, particularly high power devices

UV-VIS Spectrophotometer (UV-VIS 2410 PC) was used for reflectance studies of samples. Figure 10 shows reflection measurements of Si wafers before and after surface texturing. A representative value of surface roughness and percentage reflectance at 800nm is given in Table 2.

We have now discussed the two extremes in electronic materials; a conductor, and an insulator we will now move to a material that lies in between these two, a semiconductor. The
