WebUnlike a laser diode where the pn junction is forward biased, a photodiode requires a reverse bias of the pn junction. As illustrated in Fig. 4.1.2, consider a reverse bias voltage V B applied on a pn junction, the potential barrier across the junction is increased from ΔV pn to ΔV pn + VB. WebForward bias or biasing is where the external voltage is delivered across the P-N junction diode. In a forward bias setup, the P-side of the diode is attached to the positive terminal and N-side is fixed to the negative side of the battery. Here, the applied voltage is opposite to the junction barrier potential.
