(Nanowerk News) This will potentially allow them to create more compact and efficient elements for lasers, sensors, and optical chips. Moreover, it proves the hypothesis that ITMO physicists had about ...

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...

Researchers report the development of ultrahigh refractive index metamaterials which are integrated with a low refractive index polymer producing distributed Bragg reflector (DBR). The highest ...

Among the various sensing modalities available for bioprocess operations, index of refraction (IoR) is intriguing for its simplicity and capability for sample-less, real-time readout. A group led by ...

Although we generally assume that opacity is the normal look for animals like us humans, this factoid is only correct for as long as you maintain the dissimilar optical refraction indices of skin and ...

Toyohashi University of Technology researchers in collaboration with Massachusetts Institute of Technology (MIT), have developed a new material capable of retaining high transmissivity after thermal ...

Researchers reported a novel technology enhancing the high transparency of refractive polymer film via a one-step vapor deposition process. The sulfur-containing polymer (SCP) film produced by ...

The negative refraction of electrons in graphene has been seen for the first time in experiments done by physicists in the US. The work represents an important advance in the fabrication of graphene ...
