Researchers at Heriot-Watt University in Edinburgh, UK have developed a new design for optical tweezers using a single diode-coupled multicore fiber. The novel method promises a much more flexible ...

Introduction to the Diode Laser Researchers have been developing different types of coherent light sources to fit a larger span of applications since 1960. Present-day lasers vary in size, power-range, and ...

Photonics Technologies in Farming Farmers everywhere face the same daunting task: the world population is growing at an exponential rate, and food supply has to keep up. There is practical limits to a ...

What is Electro-Optics? In the last 20 years or so, the field of electro-optics has become increasingly important. It is often challenging to predict the future of scientific discoveries and their relevant ...

Introduction X-rays are one of the most versatile forms of radiation.  The rays can penetrate thick objects without absorbing or scattering, rendering them extremely useful for imaging purposes. X-ray ...

Introduction to Prisms Even as early as in the 13th century, six-sided crystals of natural quartz were used to generate rainbows. In the late 1660s, people believed that color was a mixture of lightness ...

Introduction to Diffraction Gratings Diffraction gratings are optical components that diffract and separate light into several beams at different angles by wavelength. Their working principle is hinged ...

Introduction to Optical Parametric Oscillators In 1961, Peter Franken and his group at the University of Michigan were the first to use  nonlinear materials to produce optical harmonics. This method ...

Forensic science has come a long way since the 700s, when the Chinese first established the concept of utilizing fingerprints as means of identification. Since then, technology in photonics and optics ...

Introduction A single human hair is approximately 80,000-100,000 nanometers wide. Now, imagine a distance that measures several hundred times smaller than a human hair. Such small distances are often ...
