▶ The photodetector that reacts to
IR radiation.
▶ The two main types of detectors are
thermal(1) and photonic(2).
√ What is Infra-red radiation?
▶ long wave length (0.75㎛ ~ 1000 ㎛)
▶ invisible to human eyes
▶ small energy
▶ emitted from all kinds of objects
▶ Broad intrinsic layer between P-N junction.
▶ High resistivity in I-region by low carrier
concentration
▶ Reverse bias make i-region fully depleted
▶ Photovoltaic effect
▶ Resistivity reduced according to the
Intensity of light
▶ Shorter distance between electrodes and
wider sensor width for better sensitivity
▶ Serpentine structure
√ Characteristics of IR radiation
▶ Invisible to human eyes
▶ Small energy
▶ Long wavelength
▶ Emitted from all kinds of objects
√ A wide variety of applications
√ New applications are constantly
being developed
