Product Overview:

Using an SOA-PULSE Unit to Create a High Performance Fiber Optic Modulator:

The SOA pulse driver allows the user to employ a semiconductor optical amplifier to create a high speed, high dynamic range fiber optic modulator. It is a high performance alternative to an AOM or an EOM fiber modulator.

A CW laser diode is used as the input to the SOA. When the bias current driving the SOA is switched ON/OFF in a pulsed mode (with adjustable speed up to > 1 GHz), the result is a fiber optic modulator which offers multiple advantages over traditional modulator technologies. These units can be configured for wavelengths from 750 nm to 1700 nm. It is a lossless, high extinction ratio and highly polarized modulator solution.

The "SOM" Semiconductor Optical Modulator:

When configured with a CW laser diode input and with and an SOA installed in the pulser, the user creates an "SOM". SOM stands for semiconductor optical modulator. Here are a few of the many advantages an SOM offers relative to an AOM, EOM or directly pulsed laser diode solution:

  • The dynamic range of an SOM is higher than that of an EOM or an AOM. An AOM / EOM is typically limited to < 30 dB, and often less since there is a strong polarization dependency. An SOM offers a higher dynamic range, typically > 48 dB with a high extinction ratio > ~ 50 dB

  • An SOM has no polarization rotation dependencies, whereas both an EOM and an AOM typically are highly susceptible to polarization dependencies

  • The spectrum of an SOM remains the same along the entire pulse, whereas when directly pulsing a laser diode, the user must consider the undesirable spectral effects which can occur from coupling of the frequency/phase spectrum and intensity profile

  • The SOM is the only commercially available solution which also functions as an optical isolator for the laser input source
