Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation01:26

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy  (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used.

Area of Science:

  • Optoelectronics
  • Semiconductor Devices
  • Photonics

Background:

  • Semiconductor optical amplifiers (SOAs) are crucial for optical communication systems.
  • Quantum-dash (Qdash) structures offer unique optical properties compared to quantum wells.
  • Optimizing Qdash SOAs requires understanding the impact of layer density on performance.

Purpose of the Study:

  • To compare the performance of InAs/InP quantum-dash semiconductor optical amplifiers (SOAs) with varying numbers of dash layers.
  • To identify the optimal number of dash layers for specific performance metrics.
  • To evaluate the potential of these SOAs for uncooled applications.

Main Methods:

  • Fabrication of identical Qdash SOAs with 3, 5, 8, and 12 InAs dash layers on InP substrates.
  • Characterization of amplified spontaneous emission (ASE) power, chip gain, ASE bandwidth, 3 dB gain saturated output power, noise figure (NF), and gain peak wavelength.
  • Performance evaluation under a 300 mA CW bias current and at 25 °C.

Main Results:

  • The eight-layer Qdash SOA exhibited the highest amplified spontaneous emission power (4.3 dBm) and chip gain (26.4 dB) at 1550 nm.
  • SOAs with fewer layers (e.g., three-layer) showed wider ASE bandwidth (90 nm) and higher 3 dB saturated output power (18.2 dBm).
  • Noise figure increased with the number of dash layers, while the 12-layer device had the longest gain peak wavelength (1570 nm).
  • The five-layer Qdash SOA demonstrated balanced performance with 25.4 dB gain, 15.2 dBm output power, and 5.7 dB NF.
  • Performance surpassed that of reported quantum well SOAs.

Conclusions:

  • The number of InAs dash layers significantly influences the performance characteristics of Qdash SOAs.
  • Specific layer counts are optimal for different applications, balancing gain, bandwidth, and noise.
  • InAs/InP Qdash SOAs demonstrate high performance suitable for uncooled applications with diverse requirements.
