    Abstract:

    The design principle of a single-mode arrayed-waveguide grating multiplexer with flat spectral response is proposed on the basis of a discrete Fourier transform. By a beam propagation-method simulation, a flat spectral region (within 1-dB loss increase) is obtained over 57.2 GHz for 100-GHz channel spacing.

    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.
