Description
TECHNICAL FIELD
[0001] The utility model relates to waveguide grating cleaning field especially relates to a fixture for no thermal array waveguide grating chip end face external inspection cleaning. BACKGROUND
[0002] At present, the optical fiber communication technology develops extremely fast, wherein the WDM (Wavelength Division Multiplexing) system is the most common optical layer networking system at present, which realizes multi-channel signal transmission through multiplexing and demultiplexing. The AWG (Arrayed Wavelength Grating) based on the PLC (Planar Lightwave Circuit) technology is an important multiplexer / demultiplexer device in the WDM system.
[0003] The arrayed waveguide grating can be called the key device most suitable for the large-capacity dense wavelength division multiplexing (DWDM) system due to the advantages of uniform channel loss, small size, easy integration, convenient batch production and various temperature compensation devices, which enable the arrayed waveguide grating to be made into a passive device meeting the working temperature of-40~85℃.
[0004] The existing arrayed waveguide grating realizes the working temperature of-40~85℃ by bonding the optical chip with the metal plate with the temperature compensation device. This kind of arrayed waveguide grating is generally coupled with the array plate after forming the assembly by bonding the metal plate, and the input / output end face of the arrayed waveguide grating chip needs to be externally inspected and cleaned before coupling.
[0005] The existing external inspection and cleaning process is generally to hold the arrayed waveguide grating assembly under the optical microscope for observation and processing. Since the input / output coupling end face of the arrayed waveguide grating chip and the upper and lower surfaces of the chip have a structure similar to a trapezoid, the hand-held assembly observation needs to frequently adjust the hand-held angle, which increases the operation difficulty and operation time of the external inspection and cleaning.
