Daniel from the article,

Optical Modulators
One fundamental difference between Broadcom’s scheme and Nvidia’s is the optical modulator technology that encodes electronic bits onto beams of light. In silicon photonics there are two main types of modulators—Mach-Zehnder, which Broadcom uses and is the basis for pluggable optics, and microring resonator, which Nvidia chose. In the former, light traveling through a waveguide is split into two parallel arms. Each arm can then be modulated by an applied electric field, which changes the phase of the light passing through. The arms then rejoin to form a single waveguide. Depending on whether the two signals are now in phase or out of phase, they will cancel each other out or combine. And so electronic bits can be encoded onto the light.

Microring modulators are far more compact. Instead of splitting the light along two parallel paths, a ring-shaped waveguide hangs off the side of the light’s main path. If the light is of a wavelength that can form a standing wave in the ring, it will be siphoned off, filtering that wavelength out of the main waveguide. Exactly which wavelength resonates with the ring depends on the structure’s refractive index, which can be electronically manipulated.

However, the microring’s compactness comes with a cost. Microring modulators are sensitive to temperature, so each one requires a built-in heating circuit, which must be carefully controlled and consumes power. On the other hand, Mach-Zehnder devices are considerably larger, leading to more lost light and some design issues, says Schow.

This is where LWLG comes to the rescue!!!

LWLG to the rescue of Intel/Ayar/GF!!! Today, silicon microring modulators are perceived as promising to implement such links; however, they provide limited bandwidth and need thermal stabilization systems.

Confirmation on what ole Proto been telling y'all here!!!

LWLG has NO COMPETITION!!!!
NOTHING EVEN CLOSE!!!!

White Paper - Hybrid Integration of Exotic Materials in CMOS Platform

This white paper marks the first direct evidence of a connection between GlobalFoundries, (Intel)Ayar Labs, and EO polymers.

Intel/Ayar MRR fatal issues solved by LWLG Polymers, just read posts #133274_#133275_#133276 and understand the following about the position LWLG is currently in, here to summarize for you,

#133274 Intel/Ayar for many years now have focused on their Next-Gen Photonics solution using silicon based MRR's, but there is an inherent problem with this technology, temperature control, which cannot be solved, at least not economically, read this to better understand,
https://investorshub.advfn.com/boards/read_msg.aspx?message_id=171251782

#122275 LWLG Polymers CAN solve the issues that Intel/Ayars cannot, therefore it is a strong probability that Intel/Ayar and LWLG are working together under NDA's currently, read this to better understand,
