Latest Patents

Nadav Bar-Chaim's most recent patents include the groundbreaking "Superluminescent diode and single mode laser." This invention features a buried heterostructure window device, which comprises an elongated layer of gain medium surrounded by a medium with a lower index of refraction. This design is paramount for guiding light effectively along the length of the gain medium. Notably, a window and an antireflective layer are strategically deposited at the output end to minimize reflections, enhancing performance.

The device operates by electing to pump a portion of the gain medium nearer to the output end while leaving the remote end unpumped. The absorption properties of the unpumped medium play a crucial role in inhibiting reflections and enabling strong superluminescent output when pumped at moderate power levels. Furthermore, when pumped above the lasing threshold, the device can convert to a single mode laser, which features side band power that is significantly lower than that of the principal oscillation mode. This innovative technology demonstrates a nuanced understanding of optical physics and device engineering.
