Abstract
An optical isolator (10) includes an opto-electronic emitter (16) and an opto-electronic detector (17) mounted over offset portions (12, 13) of a leadframe (11). The offset portions (12, 13) form angles (14, 15) with other portions (24, 25) of the leadframe (11). An optically transmissive material (22) encapsulates the opto-electronic emitter (16) and the opto-electronic detector (17), and a reflective material (20) is located above the opto-electronic emitter (16) and the opto-electronic detector (17). An optically insulative packaging material (26) encapsulates the optically transmissive material (22).
