Product Overview:

A Semiconductor optical modulator (SOM) utilizes an SOA as a light modulator. A CW laser diode signal is applied to the SOA, and the bias current driving the SOA is switched ON/OFF in a pulsed mode at very high (more than 1 GHz). This modulated signal can also be customized and shaped to accommodate many emerging applications.

Advantages of the SOM compared to other modulation solutions:
• The dynamic range of a SOM is much higher than that of an EOM or an AOM. An AOM or EOM are typically limited to < 30 dB, and often less since there is a strong polarization dependency.

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

• The spectrum of a 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 input laser source.
