Perjury is a criminal offense, so only the DA can prosecute someone for perjury. If you have proof of perjury file a complaint with the DA in the county in which the crime of perjury occurred.
As a private individual you cannot 'file' criminal charges against anyone. You can attempt to bring the facts to the attention of the prosecutor's superiors - if you can present enough proof, perhaps they will institute a charge of perjury. HOWEVER you can file a civil suit against the prosecutor for false or malicious prosecution.
Contact your local prosecuting attorney.
The same as you do anywhere else. You must present evidence or proof that refutes the perjured item, or testimony. If the perjury affected the outcome of a judicial action, you will have to file a motion to re-open the case based on new evidence.
Inform your attorney, who can refer the matter to the Prosecution's attention. If it can be proven, then a charge of Perjury may be brought against the officer. Without proof of a deliberate lie, it is simply up to your side to refute the officer's statement with other testimony.
You need evidence to prove any charge.
