I&rsquo;ve attached a PowerPoint and my simulation file for your reference. In my simulation, I don&rsquo;t use a shutter step for on\/off; instead, I use the transient simulation by adjusting the time on\/off as shown in the figs in the PowerPoint <a title=\"Thermal time constant\" href=\"https:\/\/drive.google.com\/file\/d\/1LN_NG5NwpR3mZX89tWDZ4yIk4q4bE1Tp\/view?usp=drive_link\" rel=\"nofollow external noopener\">https:\/\/drive.google.com\/file\/d\/1LN_NG5NwpR3mZX89tWDZ4yIk4q4bE1Tp\/view?usp=drive_link<\/a>. For measurement, the photonic chip is mounted on a PCB with a gold exposed pad, but there&rsquo;s no metal pad inside the chip for heat dissipation. The chip is wire-bonded with silver glue to the PCB and exposed pad. The PCB is on a temperature-controlled stage. I apply a pulse voltage with a 10 ns rise\/fall time to the heater and measure the rise and fall time constants. Please let me know if you have any other questions and I look forward to your opinion as this is crucial for my analysis.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-381367","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/381367","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/381367\/revisions"}],"predecessor-version":[{"id":381368,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/381367\/revisions\/381368"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=381367"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
