06_EOModulators_1201-1207.qxd.P:1201-1207 7/25/11 4:20 PM Page 1205 Fiber CHAPTERS 40 GHz Phase and Intensity Modulators The LN05S, LN27S, and the LN66S are 40 GHz Modulators manufactured by Thorlabs Quantum Electronics (TQE). These three revolutionary, titanium-indiffused Z-cut lithium niobate, high-performance optical modulators are designed for ease of system integration; they offer large bandwidths and are ideal for developing high-speed modulation systems. LN05S-FC 40 GHz Intensity Modulator The LN05S intensity modulator with external DC bias is a high-performance 40 GHz (40 Gb/s) modulator that has a single-ended drive configuration with a fixed chirp coefficient of ±0.7 and an industry-leading low RF drive voltage (5.5 V). The LN27S and the LN66S phase modulators are high-performance, 40 GHz (40 Gb/s) modulators that enable chirp control in high-speed data communications. These modulators are also ideal for applications in coherent communications, sensing, all-optical frequency shifting, and data encryption. While the LN27S and LN66S modulators both offer internal RF terminations, the LN27S also offers an optical polarizer not included with the LN66S. With no polarizer, the LN66S is capable of supporting both optical modes, ordinary and extraordinary. Each mode will have a different modulation efficiency; ITEM # LN05S LN27S / LN66S the modulation efficiency (Vπ) of the Parameter Min Typical Max Min Typical Max extraordinary mode will be approximately Operating Wavelengtha 1525 nm – 1605 nm 1525 nm – 1605 nm a factor of three greater than the ordinary Optical Insertion Loss (Connectorized) – 4.0 dB 5.0 dB – 4.0 dB 5.0 dB mode.
