PWDM Pigitial Photodiode Characteristics
Responsivity
Responsive of a PWDM pigitial photodiode is defined as the ratio of the photocurrent produced in the photoconductive mode to the burst illumination, expressed in amperes per watt (A/W). The response characteristic can also be expressed as quantum efficiency, that is, the ratio of the number of carriers generated by illumination to the number of burst illumination photons.
Dark current
In photoconductive mode, the current through the PWDM pigitial photodiode is defined as a dark current when no light is received. Dark current in PWDM pigitial photodiode includes radiation current and saturation current of the semiconductor junction. The dark current must be measured in advance, especially when PWDM pigitial photodiodes are used for precise optical power measurements, and errors due to dark current must be carefully considered and corrected.
Equivalent noise power
Noise-equivalent power (NEP) refers to the minimum optical power required to generate photocurrent, which is equal to the rms value of noise power at 1 Hz. A related property is called detectivity (D), which is equal to the inverse of the equivalent noise power. The equivalent noise power is approximately equal to the minimum detectable input power of the PWDM pigitial photodiode.
Basic Principles of PWDM Pigitial Photodiode
PWDM pigitial photodiodes operate based on the photovoltaic effect. When photons (light particles) strike the semiconductor material (e.g., silicon, indium gallium arsenide), they generate electron-hole pairs. This creates a measurable current proportional to the light intensity. In optical transceivers, this process enables the conversion of modulated light pulses into digital electrical signals.
Light Absorption
Light enters the PWDM pigitial photodiode through the optical fiber.
Carrier Generation
Photons are absorbed by the semiconductor, creating charge carriers.
Current Flow
An external circuit measures the resulting current for signal processing.
