40Gb/s DQPSK Receiver
-
The integrated DQPSK receiver incorporates an optical phase demodulator (delay-line interferometer or DLI) with 2 pairs of balanced photo-diodes and 2 linear TIAs into a single butterfly package. Compared with the currently available discrete solution in which a separate DLI and a separate receiver are used, the integrated DQPSK receiver eliminates labor intensive fiber routing and coupling (between the DLI and the balanced receiver) as well as the skew control. Moreover, the integrated DQPSK receiver offers a smaller footprint suitable for today’s demanding high speed transponder applications.

Optics
-
Welcome to Thorlabs; below you will find links to optical components and systems, a subset of our entire line of photonics products. All single element optical components can be found under the optical elements link with the exception of optical components that have polarization properties since they have a separate link. Multi-element systems like beam expanders and objective lenses as well as interferometers, fiber collimators, reference cells, modulators, and other optical devices can be found by choosing the optical systems link. Thorlabs also manufactures an extensive line of free-space and fiber optic isolators; stock items ship the same day that they are ordered while our custom orders benefit from our streamlined design and manufacturing process, which minimizes lead time.

Turning Mirror
10769A
-
The 10769A is ideal for use in laser measurement and calibration applications. In the calibration of slant bed lathes, for example, the beam steering mirror deflects the beam from the laser head upward, through the interferometer, along the lathe's cross slide. One or more mirrors can also create a path from a laser head to an interferometer located in an otherwise inaccessible position, as in the case of a milling machine with a table that moves in only one axis.

2.5G DPSK Demodulator
-
Optoplex’s Optical DPSK Demodulator, also known as Delay Line Interferometer (DLI), converts phase modulation to amplitude modulation over the entire C+L band in support of data transmission rates of 2.5, 10 or 40 Gb/s. The DPSK demodulator is designed for phase modulated optical communication systems utilized in commercial, defense and space exploration markets. The device plays a key role in improving signal quality and performance to meet the expanding demand for higher data rates and more complex transmission formats within current and next generation systems without major capital expenditure. Optoplex’s DPSK Demodulator is based on a patented free-space optical design, which is compact, athermal and polarization-independent. Themeasured frequency drift over temperature is only ~0.02 GHz/°C for our standard passive device. Further, this DPSK Demodulator exhibits a total polarizationdependent phase shift of less than 2 degrees over the entire operating temperature range with a high extinction ratio. Optoplex’s DPSK Demodulators can be configured to be fully tunable, colorless tunable or purely passive. Dual-Rate DPSK Demodulator is also available.

The Keysight 10705A Single Beam Interferometer, the smallest linear interferometer, is designed for making low mass or limited space single axis measurements. It is ideal for use in disk drive and other confined space applications. The single beam interferometer is called that because the outgoing and returning beams are superimposed on each other, giving the appearance of only one beam traveling between the interferometer and the retroreflector.

Fourier Transform Optical Spectrum Analyzer, 600 - 1700 nm
OSA202C
-
Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.
