In this article, a matched branch line‐loaded negative group delay (NGD) circuit without resistor is presented firstly, and then an Wilkinson power divider with NGD characteristic is implemented by integrating the NGD circuit and the power divider by using self‐packaged suspended coplanar waveguide (SCPW) technology. The self‐packaged SCPW power di...

As a key component of the beam splitting and combining in photonic integrated circuits, an optical power splitter requires the characteristics of compactness, broadband, and low loss. Here, we propose a ${1} \times {2}$ 1 × 2 ultra-broadband 3 dB power splitter with a 5 µm long beam splitting area, based on the structure of a subwavelength grating....
