Double Curvature Lensed Fiber
The double curvature fiber lens is mainly designed for the elliptic spot of the optical chip. The bidirectional curvature Rx and Ry of the double curvature fiber lens can effectively match the diffraction angles of the laser chip in the fast axis and the slow axis, so as to improve the coupling efficiency of the optical chip.
