Embodiment Construction
[0023] As mentioned in the background technology section, since the transmission between a certain port pair in a conventional integrated optical router is reciprocal at the same time, the output signal and the input signal have the same path, and the forward and reverse between multiple ports cannot be realized Non-reciprocal transmission, the transmission efficiency cannot be further improved. At the same time, this type of device expands the number of ports by cascading unit devices. As the number of ports increases, the number of required unit devices will increase sharply, thereby greatly increasing the device size and modulation power consumption.
[0024] The non-reciprocal optical router with a planar metalens structure based on silicon-based integration proposed by the present invention can realize multiplex working status, improve transmission efficiency, and break the optical routing network construction method of cascading unit devices at the same time, avoiding the...
