   ILX LIGHTWAVE LDT-5545B   Description / Specification:    
ILX LIGHTWAVE LDT-5545B 50W Thermoelectric Temperature Controller

The ILX Lightwave LDT-5545B is a precision; microprocessor based thermoelectric (TE) temperature controllers that deliver a low noise, bipolar constant current output of up to 5 Amps and 50W of heating or cooling power. These instruments close a precision temperature control loop through a variety of temperature sensors and display temperature from -99° C to 199° C or sensor resistance. The temperature controller topology, paired with a hybrid smart-integrator control loop result in fast settling times with a temperature stability of 0.004 C which is ideal for laser diode or optoelectronic component testing requiring stable wavelength and optical power.

Related Optical Terms and Definitions. For a complete list go to our  Terms and Definitions Page.

A change in the optical frequency caused by direct modulation of the laser. A chirp is a signal in which the frequency increases ('up-chirp') or decreases ('down-chirp') with time. In some sources, the term chirp is used interchangeably with sweep signal.

The extent to which optical power from one signal path is prevented from reaching another signal path.

Polarization Extinction Ratio
Polarization Extinction Ratio is the ratio of optical power in the slow axis of the polarization maintaining fiber to optical power in the fast axis within a specified wavelength range.

Sidemode Suppression Ratio
Sidemode Suppression Ratio is the ratio of average signal power to the optical power of the highest sidemode within a distance from 0.1 to 6 GHz to the signal’s optical frequency, expressed in dB.

Wavelength Stability
Wavelength Stability is the change of wavelength during given time span, expressed as ± half the span between the maximum and the minimum of all actual wavelengths.
