COMMUNICATIONS COMPONENTS 2x2 High Speed Lithium Niobate Interferometric Switch Key Features • High polarization extinction • Low drive voltage • Low fiber-to-fiber insertion loss • 1550 nm operation Applications The JDSU 2x2 Interferometric Switch is a high extinction, high speed switch. Because the waveguides are polarizing, control of the input light polarization is required. Switching speeds in excess of 1 ns are attainable. Input and output fibers are polarization maintaining. • Nanosecond switching Typical Return Loss Curve, S11 Typical Frequency Response, S21 42 0 Relative Detected RF (dBe) Relative Detected RF (dBe) -5 43 44 45 46 -10 -15 -20 -25 -30 -35 -40 47 0 2.00E+08 4.00E+08 6.00E+08 8.00E+08 1.00E+09 0 4.00E+08 6.00E+08 8.00E+08 Frequency (GHz) Frequency (GHz) NORTH AMERICA : 800 498-JDSU (5378) 2.00E+08 WORLDWIDE : +800 5378-JDSU WEBSITE : www.jdsu.com 1.00E+09 2X2 HIGH SPEED LITHIUM NIOBATE INTERFEROMETRIC SWITCH 2 Functional Schematic Device Schematic Applied Voltage VRF VBIAS PM Fiber In A C B D 3 dB PM Fiber Out TM APE Waveguides 2x2 Interferometric Switch Dimensions Diagram Select Optical Input Optical Output -Vπ/2 A D -Vπ/2 B C +Vπ/2 A C +Vπ/2 B D (Specifications in inches [mm] unless otherwise noted.)
