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;

All three modulators are based on Z-cut
titanium-indiffused LiNbO3 and are
hermetically packaged in a dual-port
housing with PM and SM fiber pigtails
on the device input and output,
respectively. The fiber pigtails are
connectorized with FC/PC connectors.
Please note that polarization-maintaining
fiber and a full range of connectorization
options are available for all lithium
niobate modulators. Contact Technical
Support for customization assistance.
