i think in order to population inversion in depletion region. also the laser diodes must be degenerated.

The bluk resistance of a diode depends on?
Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.
How is a non-conducting diode biased?
A nonconducting diode is biased in the reversed direction (reverse polarization).
What is a device made of semiconductor material that acts like a switch controlling the flow of electrons in a chip?
if a diode is in forward biased the diode acts as switch is on and when we apply the diode in reverse biased then it work as the switch as off.
Where can one purchase laser diode modules?
One can purchase laser diode modules on select places around the Hong Kong. OPELUS is the best place to purchase laser diode Modules, Infrared Laser Module, Green Laser Module etc.
Does the diffusion capacitance exit in forward biased diode?
Yes
What happen of a a diode When forward-biased?
when a diode is forward biased it conducts current
Which is better light emitting diode or laser diode?
Laser diode
When both junction of npn diode reverse biased the the diode in what state?
reverse biased
The bluk resistance of a diode depends on?
Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.
Which is better injection laser diode or light emitting diode?
Laser diode
Is a diode laser a nd. yag laser?
No. A diode laser is a semiconductor and Nd:YAG is a crystal.
What type of laser is a diode laser?
A diode laser. Also, a continuous wave laser.A diode laser. Also, a solid state laser.A diode laser. Also, a high efficiency laser, comparing to other types of laser.It's a semi-conductor laser
How is a non-conducting diode biased?
A nonconducting diode is biased in the reversed direction (reverse polarization).
List the two conditions under which a diode is operated?
A diode is a semiconductor material which has p region and n region. In order to "turn on" and conduct current in the forward direction, a diode requires a certain amount of positive voltage to be applied across it. An ideal diode conducts only when the diode is forward biased, and then the voltage drop across the diode (Vd) is zero. When the ideal diode is reverse biased, no current flows. The two conditions to operate a diode are: (a) Current flow is permitted; the diode is forward biased. (b) Current flow is prohibited; the diode is reversed biased. When the polarity of the battery is such that current is allowed to flow through the diode, the diode is said to be forward-biased.
In which configuration does a diode conduct?
Forward biased is the configuratiuon that a diode conducts.
When the both junction of NPN diode is reverse biased then the diode is mode?
cutoff
How much voltage appears across a zener diode when it is forward-biased?
That depends on the zener voltage rating:"low voltage" zeners are just a simple single diode, the zener diode"high voltage" zeners contain 2 back to back diodes in one package, the zener diode and an ordinary diode that is reverse biased when the zener diode is forward biased to block forward conduction of the zener and protect it from overcurrent damage if installed backwards by mistakeThus in "low voltage" zeners when forward biased they will have a normal diode drop (e.g. 0.7V), but "high voltage" zeners when "forward biased" they will act open due to the reverse biased blocking/protection diode in series with the zener.
