This review analyzes III-V monolithic integrated tunable lasers, highlighting design principles, performance trade-offs, and ...

Abstract: A simplified beamforming architecture using a wavelength-selective optical true time delay (OTTD) module is proposed for phased array antenna (PAA) systems. Based on diffraction order ...

Flexible, and easy-to-use Python diffraction simulator that focuses on visualizing physical optics phenomena. The simulator uses mainly scalar diffraction techniques for light propagation, provides a ...

An international team led by the Max Born Institute has developed a new type of momentum microscopy to image magnons—the ...

We’ve seen just about every possible way to make a clock here at Hackaday over the years. So it’s rare to have a first, but here we are with [Twisted & Tinned], who’s made a novel clock with a ...

The innovative AOFS-IC architecture enables fully optical-domain sensing, achieving remarkable speed and accuracy for ...

Abstract: In this letter, we report on the inscription of a fourth-order fiber Bragg grating made line-by-line in the optical fiber using a femtosecond laser. Strong Bragg resonance (~17 dB) and low ...
