I would change your observation from "this patent is very important" to "this patent is extremely important".
It is fundamental to the platform. Industry can now see for the first time the “how and why” this platform can achieve the lowest insertion loss without the need for active alignment and lenses.
Thick waveguide cores can be susceptible to multiple optical propagation modes, particularly in thick planar waveguides, and more particularly in thick planar waveguides with curvature, and as such are susceptible to high levels of signal loss. To overcome the potential for incoming signal loss, and to overcome the potential for propagation in undesirable modes, incoming signals are transferred from an optical fiber to the thick bottom core, and then to a thinner upper core designed for single mode propagation of the transferred optical signals. The stable, single mode propagation in waveguides such as that of the upper core is preferable for processing of the encoded optical signals in the PICs.
Hello Rockley...now people will know why POET's OI platform is superior.
It also provides the “how” they separate wavelengths in an industry first fabrication flow for the lowest cost and smallest footprint CWDM filtering.
The input to an arrayed waveguide, in some embodiments, is a multiplexed optical signal consisting of a number of distinct wavelengths of light. In an exemplary embodiment, the incoming optical signal is a composite signal of 16 wavelengths, centered around a wavelength of 1550 nm with increments of 20 nm between each sub-signal of the combined incoming signal. Other wavelengths and spacings between wavelengths are used in other embodiments. Typical wavelengths of light that are commonly used in optical communication networks are in the range of 1200 to 1700 nm. A commonly used wavelength, for example, is 1550 nm. In an embodiment, the incoming optical signal 502 is a multiplexed signal, and consists, for example, of a set of 16 different wavelengths, centered around 1550 nm in increments of 20 nm. In another embodiment, the incoming optical signal is a multiplexed signal consisting of eight wavelengths of light, centered around 1300 nm, in increments of 20 nm. In yet another embodiment, the incoming optical signal 502 is a multiplexed signal consisting of four wavelengths centered around 850 nm in increments of 15 nm. An arrayed waveguide provides a means for separating the various wavelengths in the incoming optical signal, and then providing distinct physical channels within which to direct the individual signals. In this example, the circuit contains sixteen output fibers 582, for example, to provide a unique channel for each of the demultiplexed wavelengths from the incoming signal 502.
