Transistor lasers are semiconductor devices that work like transistors but have an electrical output and an optical output rather than the usual two electrical outputs.…

A hybrid silicon laser is a semiconductor laser made of silicon as well as group III-V semiconductor materials. It is a type of laser that…

A material’s thermo-optic coefficient is the change in refractive index as a function of temperature. This value is likewise affected by the material’s current temperature…

One of two mechanisms that cause the power spectrum of synchrotron radiation to drop at very low frequencies is cyclotron turnover. Synchrotron self-absorption is the…

An electrochromic device (ECD) regulates optical properties such as optical transmission, absorption, reflectance, and/or emittance in a continuous but reversible manner when a voltage is…

The acousto-optical spectrometer (AOS) is based on the diffraction of light by ultrasonic vibrations. It is a sort of optical device used to analyze the…

A biosensor is an analytical device for detecting chemical substances that combines a biological component with a physicochemical detector. It is a device that combines…

Bio-inspired robotic movement is a relatively young subcategory of bio-inspired design. It is about learning insights from nature and applying them to the design of…

Tillage erosion is a type of soil erosion that occurs in cultivated areas due to soil movement caused by tillage. It is also known as…

Convertible husbandry is a flexible or adaptable approach to animal farming or agriculture in which the methods used can be modified or transformed in response…

An ecotone is a zone of transition between two biological communities where the two communities meet and merge. It is a zone where the traits…
