Abstract: A system for switching and collating light contains a focusing lens that focuses a laser. A first linear polarizer receives the focused beam and transmits the focused beam incoming light, polarized at plus 45 degrees, to a Pockels cell. The Pockels cell contains: a first Pockels cell crystal that follows the first linear polarizer; a first internal birefringent crystal plate that compensates for birefringence of the first Pockels cell crystal; a second internal birefringent compensation crystal plate that follows the first plate; and a second Pockels cell crystal, that follows the second plate. The second plate considerably compensates for birefringence of the second Pockels cell crystal. A second linear polarizer receives light from the Pockels cell and transmits light best if the light is polarized at minus 45 degrees to an optical fiber.

Abstract: Synthetizing a hardware description language code into a netlist comprising loads and a multi-clock buffer (MBUF). The MBUF receives a global clocking signal and generates a first and a second related clocking signals. The loads are grouped into a first and a second groups receiving the first and the second clocking signals respectively. A first/second clock modifying leaf are placed between a common node and the first/group groups respectively, wherein the common node is positioned closer in proximity to the first/second groups in comparison to a clock source generating the global clocking signal. The first/second clock modifying leaves receive a least divided clocking signal from the MBUF and generate the first/second clocking signals respectively. The least divided clocking signal is routed from the MBUF to the first/second clock modifying leaves. The first/second clocking signals are routed from the first/second clock modifying leaves to the first/second group respectively.
