“…However, shortening the crystal length in the WOC pair usually requires increasing the number of crystals to increase the total interaction length, which usually becomes non-practical for conventional WOC in independent crystals due to the increase of the inserting losses and the inconvenience in use. Recently, bonded WOC composites have attracted more and more attention because the monolithic WOC structure is easy to use and can significantly reduce the inserting losses [5,6]. More importantly, a large number of thin crystals can be used now in WOC to improve the device performance more significantly as well as the phase-matching type.…”
