Latest Patents
One of Nirmal's latest patents is titled "Methods and apparatus for improving reliability of an optical device using auxiliary lasers in a photonic integrated circuit." This invention discloses an optical device that includes a self-repair component capable of curing defective components. To enhance reliability and manufacturing yield, the photonic integrated circuit (PIC) serves as a multi-channel optical line terminal (OLT) and contains spare or standby lasers designed to replace any failed lasers. The PIC comprises a set of fixed-wavelength lasers (FWLs), a tunable-wavelength auxiliary laser (TWAL), a photonic detector, and a tuner. The FWLs generate optical wavelengths that represent optical signals, while the TWAL produces an optical signal with a spectrum of wavelengths based on a setting from the tuner. The photonic detector identifies defective wavelengths, and the tuner adjusts the output wavelength of the TWAL accordingly. Additionally, the PIC can include a working laser array, standby laser array, and spare laser array to provide two-layer laser defective protections.
