We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi Guilin,

Thank you for your suggestion!

For the source, we use ports directly, shown below.

For the strange phase change, we have double checked both the real and imaginary parts and found it is not a 2pi jump, but slightly (sub-rad) phase change in the range L=1.6~1.8um.
