Optical bandwidth and electrical bandwidth
WebTherefore, when the optical power spectrum has dropped to its -3dB point, the corresponding electrical power spectrum has dropped to its -6dB point at exactly the … WebThis is called the electro-magnetic spectrum and the optical spectrum for an optical device refers to the bandwidth (or range of colours) that it produces or is most sensitive to. For an LED, how quickly you can "modulate" the light level with an electrical signal is related to the electrical bandwidth of the device.

WebThe LED 3-dB modulation optical bandwidth is defined as the modulation frequency at the LED power transfer function is reduced by 3 dB [1]. The LED 3-dB modulation optical bandwidth could be expressed as: ƒ 3dB = √3 / 2π / ( Tn + TRCn ). We would like to demonstrate the modulation response properties of the LED. The project is depicted in … Webto understand and confidently calculate optical and electrical bandwidth for an optical channel. Optical bandwidth is defined as the frequency at which half the optical power is incident in the channel. Since power is measured in Watts we use 10*log 10(W/W o) to find the -3dB point. This is referred to as the optical decibel (dBo).
