A laser radar, or 'lidar' system, employs an asymmetric single-ended detector to detect received signals reflected back from targets. The asymmetric single-ended detector benefits from a reduced part count and fewer optical splices while nearly achieving a same gain as a symmetric differential detector.

System and method for using combining couplers with asymmetric split ratios in a lidar system

An arrangement is provided for a configurable optical add/drop multiplexer (OADM) assembly. The configurable OADM assembly comprises at least one configurable optical add/drop multiplexer (C-OADM) device and at least one optical switch associated with the C-OADM devices (the minimum configuration is only one C-OADM with bypass (expansion) switches). The switches can be configured so that some of the C-OADM devices can be selected to carry out wavelength operations. Each of the selected C-OADM devices may be further configured to perform wavelength manipulations such as dropping a wavelength channel, tapping a wavelength channel, adding a wavelength channel with full power level, and a combination thereof.
