Lens curing device and method for multi-channel optical module

A lens curing device for a multi-channel optical module, which cures a lens after arranging the lens on multiple axes between a laser diode and an optical waveguide of the optical module for each channel, the lens curing device comprising:

• a vacuum collet having an adhesive member configured to adhere and pick up the lens;
• a driver configured to move the vacuum collet and arrange the moved vacuum collet at an arrangement position of a submount;
• and
• an optical fiber embedded in at least a portion of the vacuum collet while connected to an ultraviolet (UV) light source in a preset wavelength band and configured to transmit light radiated from the UV light source to a UV epoxy applied to a lower end of the lens,
• wherein the adhesive member includes polydimethylsiloxane (PDMS) that is a transparent material that allows UV light to be transmitted.

A lens curing method for a multi-channel optical module, in which a lens is cured after arranging the lens on multiple axes between a laser diode and an optical waveguide of the optical module for each channel, the lens curing method comprising:

• an operation (first operation) of picking up the lens through a vacuum collet into which an optical fiber connected to an ultraviolet (UV) light source in a preset wavelength band is inserted;
• an operation (second operation) of applying a certain amount of a UV epoxy to a lower end of the picked-up lens and moving the lens to an arrangement position of a submount;
• an operation (third operation) of radiating UV light toward the UV epoxy applied to the lower end of the lens in a state in which the lens is disposed at the arrangement position;
• and
• an operation (fourth operation) of monitoring an output state of the UV light.
