A triplexer chip with cascaded butterfly multimode interference couplers by femtosecond laser microprocessing
A triplexer chip utilizing three cascaded butterfly multimode interference (MMI) couplers to output three optical signals from their respective ports is proposed. The chip consists of a borosilicate glass substrate, a JA photoresist core layer, and an RZJ photoresist cladding. The beam propagation method (BPM) is used to design and optimize the chip. The femtosecond laser processing is investigated, and the chip is processed with a laser power of 1.6 mW and an ablation speed of 4 mm/s. Tests show that the chip meets the design specifications with a low insertion loss of 4.34 dB, an extinction ratio of more than 15 dB, a crosstalk of less than −15 dB, and a 3 dB bandwidth up to 76.8 nm.
