   Keysight (Agilent) 8168F   Description / Specification:    
Keysight (Agilent) 8168F 1450 to 1590 nm Tunable Laser Source

The HP 8168F tunable laser source is a basic tool for characterizing and testing optical amplifiers and components. The current values of wavelength and output power are indicated on a large and bright display. You can select both parameters independently within the specified range. If you change the output power, the wavelength remains stable, and if you change the wavelength, the output power remains stable. Just input a new wavelength and the instrument will set it immediately. With its coherence control mode made active, the HP 8168F will feature an effective linewidth of up to 500 MHz, thus drastically reducing the interference ripple. The internal modulation frequency is selectable between 250 Hz to 300 kHz for squarewave signals with 100% modulation depth (on/off). In the external modulation mode, the bandwidth is between 200 kHz and 20 MHz with a duty cycle depending on the input signal and a maximum modulation depth of ±15%. Specifications.

Coherence Time
Average time for the wave train to lose its phase realtionships

Fiber Bragg Grating (FBG)
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the refractive index of the fiber core, which generates a wavelength specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another. Adding information into pulses of light.

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, such as a fiber optic transmission system, remains fixed with the passage of time or with varying environmental conditions.
