Semiconductor Optoelectronic Devices: Definition, Properties, and Types
In this section, you will learn about the definition, properties, and types of semiconductor optoelectronic devices.
Definition of Optoelectronic Devices and Semiconductors
Optoelectronic devices are devices that use light to transmit or receive information. They can convert electrical signals into optical signals or vice versa. They can also manipulate or process optical signals in various ways.
Semiconductors are materials that have electrical conductivity between that of metals and insulators. They can be doped with impurities to create regions with different types of charge carriers: electrons (n-type) or holes (p-type). They can also form junctions between n-type and p-type regions that allow current to flow in one direction only.
Semiconductor optoelectronic devices are optoelectronic devices that use semiconductors as their active medium. They exploit the unique properties of semiconductors such as band gap, carrier recombination, quantum confinement, and heterostructure to achieve various optical functions.
Properties of Optoelectronic Devices
Optoelectronic devices have several properties that make them useful for various applications. Some of these properties are:
Light emission: Some optoelectronic devices can generate light from electrical energy. This is achieved by injecting electrons and holes into a semiconductor region where they recombine and emit photons. The wavelength of the emitted light depends on the band gap of the semiconductor material. Examples of light-emitting optoelectronic devices are laser diodes and light-emitting diodes (LEDs).
Light absorption: Some optoelectronic devices can absorb light and convert it into electrical energy. This is achieved by exposing a semiconductor region to light where photons are absorbed and create electron-hole pairs. The generated charge carriers can be collected by applying an external voltage or current. Examples of light-absorbing optoelectronic devices are photodetectors and solar cells.
Light modulation: Some optoelectronic devices can modulate the intensity, phase, frequency, or polarization of light. This is achieved by applying an external electric field or current to a semiconductor region where the optical properties such as refractive index or absorption coefficient are changed. Examples of light-modulating optoelectronic devices are electro-optic modulators and electro-absorption modulators.
Light amplification: Some optoelectronic devices can amplify an optical signal by providing additional energy to it. This is achieved by injecting electrons and holes into a semiconductor region where they stimulate the emission of photons that have the same wavelength and phase as the input signal. Examples of light-amplifying optoelectronic devices are semiconductor optical amplifiers and laser diodes.
Light detection: Some optoelectronic devices can detect an optical signal by measuring its intensity, phase, frequency, or polarization. This is achieved by exposing a semiconductor region to light where photons are absorbed and create a change in voltage or current that can be measured by an external circuit. Examples of light-detecting optoelectronic devices are photodetectors and photodiodes.
Types of Optoelectronic Devices
There are many types of optoelectronic devices that perform different functions based on their structure and operation. Some of the common types are:
Laser diodes: These are optoelectronic devices that emit coherent light with high intensity and narrow linewidth. They consist of a p-n junction with a cavity that acts as a resonator for the emitted photons. The cavity has two mirrors at its ends that reflect the photons back and forth until they reach a threshold for stimulated emission. Laser diodes can be edge-emitting or vertical-cavity surface-emitting (VCSEL).
a p-n junction with a large band gap that emits photons when electrons and holes recombine. LEDs can be made of various semiconductor materials such as gallium arsenide (GaAs), gallium nitride (GaN), or silicon (Si). LEDs can emit light of different colors depending on the band gap and the doping of the semiconductor material.
Photodetectors: These are optoelectronic devices that convert light into electrical signals. They consist of a p-n junction or a metal-semiconductor junction that absorbs photons and generates electron-hole pairs. The generated charge carriers can be collected by applying a bias voltage or current to the junction. Photodetectors can be classified into photovoltaic or photoconductive depending on the mode of operation.
Modulators: These are optoelectronic devices that change the properties of an optical signal such as intensity, phase, frequency, or polarization. They consist of a semiconductor region that is subjected to an external electric field or current that alters its optical properties such as refractive index or absorption coefficient. Modulators can be electro-optic or electro-absorption depending on the mechanism of modulation.
Amplifiers: These are optoelectronic devices that increase the power of an optical signal by providing additional energy to it. They consist of a semiconductor region that is injected with electrons and holes that stimulate the emission of photons that have the same wavelength and phase as the input signal. Amplifiers can be semiconductor optical amplifiers (SOAs) or laser diodes depending on the structure and operation.
Integrated devices: These are optoelectronic devices that combine two or more functions in a single device. They consist of multiple semiconductor regions that are connected by waveguides or couplers that transfer optical signals between them. Integrated devices can perform various functions such as switching, multiplexing, demultiplexing, filtering, or logic operations.
