When a beam of infrared light strikes their ultra-thin lens—barely thicker than a red blood cell—it emerges on the other side ...

Abstract: We could demonstrate a 2.0-μm wavelength superstructure grating active DBR laser with stable single mode operation and small fluctuations of light intensity 2.5 dB across a whole tuning ...

Abstract: We present a planar lightwave circuit curved 2/spl times/2 coupler. Its splitting ratio has a low sensitivity to wavelength, polarization, and fabrication yet is low-loss and compact. We ...

Fluorescent molecules that absorb and emit light in the near-infrared (NIR) and short-wave infrared (SWIR) regions have significant potential for various applications. These molecules can serve as ...

CNN political commentator David Axelrod suggested Sunday that discussions about former President Joe Biden's mental acuity should be muted and set aside in light of his recent cancer diagnosis ...

PKR deputy president Rafizi Ramli has challenged R Ramanan's claim that Nurul Izzah Anwar's leadership could secure between 70 and 80 parliamentary seats for the party. During a ceramah in Pahang ...

She saw the benefits of swapping out her high-intensity workouts for low-pressure social exercising, and she's not alone. Alternative low-pressure exercise groups are increasing in popularity with ...

A University of New South Wales (UNSW) Sydney mathematician has revealed the first successful solution of an ‘impossible’ equation once considered unsolvable. Described as algebra’s oldest problem, ...

It should be pointed out that our results did not support the notion that a single exposure to blue wavelength light during the day would lead to increased positive and decreased negative affect. Both ...
