With a total of two patents to his name, Park has demonstrated a commitment to advancing technology in this critical area.

Latest Patents

His latest patents include an add-drop wavelength filter using mode discrimination couplers and tilted Bragg gratings. This invention describes a filter that separates specific wavelength components from optical signals propagating through an optical waveguide or adds specific wavelength components thereto. Add-drop wavelength filters are essential in wavelength division optical communication systems, as they require good wavelength selectivity and stability. Previous designs faced challenges with stability and fabrication, but Park's invention utilizes mode conversion in a dual mode waveguide, resulting in low loss and enhanced stability. Additionally, the devices included in this filter are conventionally used, facilitating easy fabrication and expanding application fields through techniques like apodization and chirping of the Bragg gratings.

Another notable patent is the optical add/drop multiplexer, which features a mode converter. This multiplexer includes a first mode coupler at the input and a second mode coupler at the output of the mode converter. The mode converter consists of an optical fiber with multiple cladding modes and a single core mode guided along a core. An acoustic wave propagation member is integrated into the design, which propagates an acoustic wave from its proximal to its distal end, enhancing the functionality of the device.
