Abstract
The present invention relates to a KBBF family nonlinear optical crystal-prism coupler and its method of fabrication. The coupler comprises: a KBBF family crystal with two smooth surfaces; transition layers each of which is deposited on respective one of the two smooth surfaces of the KBBF family crystal; and a pair of prisms each of which optically contacts with respective one of the activated transition layers. The present invention further provides a KBBF family nonlinear optical crystal-prism coupler that comprises: a KBBF family crystal with two smooth surfaces; a pair of prisms each of which has a smooth surfaces; first transition layers each of which is deposited on respective one of the two smooth surfaces of the KBBF family crystal; and second transition layers each of which is deposited on a smooth surface of respective one of the pair of prisms, wherein the first and second transition layers are integral by optical contact. The coupling between the KBBF family crystal and the prisms is achieved by optical contact through transition layers to improve bonding strength.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
