Accurate Modeling of Directional Couplers With Oxide Cladding: Bridging Simulation and Experiment Directional couplers are a fundamental building block in integrated photonics, particularly in quantum ...

Explore RF directional couplers: essential measurement accessories that transform energy through clever construction techniques.

Wabtec acquires Dellner Couplers for $960m Dellner Couplers specialises in train connection systems, with production, assembly, and aftermarket services in 13 countries, serving more than 200 ...

The directional couplers have an operating frequency range from 54 MHz to 800 MHz and can be set for coupling levels from –30 dB to –70 dB with directivity of 30 dB or better. ERI also makes ...

Because the directional coupler’s loss between the incident and received power is negligible, in the first step, we measure output power using a power sensor connected to the output of the directional ...

The goal was to make much tighter directional couplers. Instead of the coupled signal being 20 dB down from the main line signal, the goal was 6 dB. The structure was to look more like this. This was ...

A directional coupler was also modeled in SEMulator3D (Figure 3) and sidewall angle variation impact on the optical properties of the device was studied. In this virtual experiment, DOE and Monte ...

Coming out of the NAB Show, it’s time to look back at things that got overlooked among the razzle-dazzle of Las Vegas. At the show Electronics Research/ERI introduced a series of directional couplers.

Researchers demonstrate unequivocal quantum interference between plasmons in a Hong–Ou–Mandel experiment. The results may be important for quantum information applications of plasmonics.
